9K114 Shturm
9K114 Shturm (Russian: 9К114 «Штурм»- "shturm" means storm (assault) in English) is a SACLOS radio guided anti-tank missile system of the Soviet Union. Its GRAU designation is 9K114. Its NATO reporting name is AT-6 Spiral. The missile itself is known as the 9M114 Kokon (Cocoon).
Development
The missile was developed by the Kolomna Machine Design Bureau, which was also responsible for the 3M6 Shmel and 9M14 Malyutka. Work on the missile began in 1967, with the hope of using the missile on Mi-24s. However, delays forced the design of an upgraded Falanga system (9M17 Skorpion) using SACLOS guidance as a stopgap. Testing of the missile was completed in 1974, and it was accepted into service in 1976. The missile has no direct western counterpart, though, in role, it is closest to the AGM-114 Hellfire, and in guidance method, to the MGM-18 Lacrosse.
It was originally given the NATO designation AS-8, before being redesignated as AT-6.
Description
The missile can be deployed on a variety of platforms, including the Mi-24V and from 1979-onwards the MT-LB based 9P149 tank destroyer. There is also a shipborne version of the missile, with the launcher holding six missiles.

Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with absorption lines. Each line indicates an ion of a certain chemical element, with the line strength indicating the abundance of that ion. The relative abundance of the different ions varies with the temperature of the photosphere. The spectral class of a star is a short code summarizing the ionization state, giving an objective measure of the photosphere's temperature and density.
Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type). Each letter class is then subdivided using a numeric digit with 0 being hottest and 9 being coolest (e.g. A8, A9, F0, F1 form a sequence from hotter to cooler). The sequence has been expanded with classes for other stars and star-like objects that do not fit in the classical system, such as class D for white dwarfs and class C for carbon stars.

Hungarian State Railways
Hungarian State Railways (Hungarian: Magyar Államvasutak or MÁV) is the Hungarian national railway company, with divisions "MÁV START Zrt." (passenger transport), "MÁV-Gépészet Zrt." (maintenance) and "MÁV-Trakció Zrt.". The "MÁV Cargo Zrt" (freight transport) is sold for ÖBB. The head office is in Budapest.
Hungary is a member of the International Union of Railways (UIC). The UIC country code for Hungary is 55.
History
Before 1900
The first steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. This date is regarded as the birth date of the Hungarian railways. The Romantic poet Sándor Petőfi, later a leader of the Hungarian Revolution of 1848, rode on the first train and wrote an occasional poem, predicting that rails would connect Hungary like blood vessels in the human body.
After the failed revolution, the existing lines were nationalized by the Austrian State and new lines were built. As a result of the Austro-Sardinian War in the late 1850s all these lines were sold to Austrian private companies. During this time the company of Ábrahám Ganz invented a method of "crust-casting" to produce cheap yet sturdy iron railway wheels, which greatly contributed to railway development in Central Europe.

Moon
The Moon (in Greek: σελήνη Selene, in Latin: Luna) is Earth's only natural satellite. It is one of the largest natural satellites in the Solar System, and, among planetary satellites, the largest relative to the size of the planet it orbits (its primary). It is the second-densest satellite among those whose densities are known (after Jupiter's satellite Io).
The Moon is thought to have formed approximately 4.5 billion years ago, not long after Earth. There are several hypotheses for its origin; the most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.
The Moon is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters. It is the second-brightest regularly visible celestial object in Earth's sky after the Sun, as measured by illuminance on Earth's surface. Although it can appear a very bright white, its surface is actually dark, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have, since ancient times, made the Moon an important cultural influence on language, calendars, art, and mythology.

Moon (visual novel)
Moon (styled as Moon.) is a Japanese adult visual novel developed by Tactics, a brand of Nexton, released on November 21, 1997 playable on Windows PCs. The game was described by the development team as a "Reaching the Heart AVG" (心に届くAVG, Kokoro ni Todoku AVG). The story follows the protagonist Ikumi Amasawa, a girl who joins an organization called Fargo in the hopes of discovering why and how her mother died, who was a member of the same group. The gameplay in Moon follows a branching plot line which offers pre-determined scenarios with courses of interaction, and focuses on the three female main characters. The game ranked twice in the national top 50 for best-selling PC games sold in Japan.
Much of the staff that created the game later became the founding members of the visual novel brand Key. Moon was the starting point for Key's origins, and was the first time the principal Key team was formed. A novel based on the game written by Midori Tateyama was released in July 1998 by Movic. The game's original soundtrack was released bundled with Dōsei's soundtrack in August 2000 at Comiket 58; Dōsei was Tactics' first game. Moon has been referenced in other media not directly related to the game, such as in Tactics' third game One: Kagayaku Kisetsu e, and in the second anime adaptation of Key's first game Kanon.

Natural satellite
A natural satellite is a celestial body that orbits another celestial body of greater mass (e.g., a planet, star, or dwarf planet), which is called its primary. For example, the Moon is a natural satellite of Earth, and Earth is a natural satellite of the Sun.
In the Solar System there are 173 known natural satellites which orbit within 6 planetary satellite systems. In addition, several other objects are known to have satellites, including three IAU-listed dwarf planets: Pluto, Haumea, and Eris.As of January 2012, over 200 minor-planet moons have been discovered. There are 76 known objects in the asteroid belt with satellites (five with two each), four Jupiter trojans, 39 near-Earth objects (two with two satellites each), and 14 Mars-crossers. There are also 84 known natural satellites of trans-Neptunian objects. Some 150 additional small bodies have been observed within the rings of Saturn, but only a few were tracked long enough to establish orbits. Planets around other stars are likely to have satellites as well, and although numerous candidates have been detected to date, none have yet been confirmed.

For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space . A star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. When the stellar core is sufficiently dense, hydrogen becomes steadily converted into helium through nuclear fusion, releasing energy in the process. According to the latest data, the observable universe contains 1×1024 stars. The nearest one to our planet is our Sun. Scientists have studied stars for quiet a time now and divided them on them on the basis of their age and temperature. We will discuss one such classification today, which is the stellar classification of stars. Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. We all see the stars twinkling but have you ever wondered how do stars twinkle? To answer this, let us go back to our school days where we were taught refraction of lights. Twinkling of stars is caused by the passing of light through different layers of a tempestuous atmosphere. But in real the stars don't twinkle, they only appear as such because of the interaction between our eyes, stars and Earth's atmosphere. The formation of a star is not a quick process, it takes around a million of years to form a star from an accumulation of gas and dust which collapses due to gravity in its nebulae. Our universe has nebulas, in which new stars are being formed all the time. Though we haven’t observed much of these stars present in our infinite universe but those which are observed give a very good idea of their composition and properties.
Now let us go back to the base of the topic Stellar Classification. It is a scheme assigning stars their type on the basis of their temperatures as calculated from their spectra. The classification of temperature is done on the basis of Wien's Law regarding black body radiation. The universally accepted system of stellar classification is a combination of two schemes, the Harvard system, which is based on the star's surface temperature, and the MK i.e. Morgan Keenan system, which is based on the stars luminosity. The MK also called Yerkes system, is the work of the American astronomers W.W. Morgan, P.C. Keenan, and few others. It is based on two sets of parameters-a refined version of the Harvard O-M scale, and a luminosity scale of grades I-for super-giants, II-bright giants, III-normal giants, IV-sub-giants, and V-main sequence, or dwarf, stars; further specifications may be used, such as a grade Ia for bright super-giants and grades VI and VII for sub-dwarfs and white dwarfs, respectively. In the Harvard system the stars are classified on as the hottest to coolest using letters such as O, B, A, F, G, K, M where O is the hottest(25,000 K) and blue in colour and M is the coolest (3,500 K) star which is red in colour. The letters are further subdivided from hot to cool. An adapted and famous mnemonic for memorising this sequence of stellar classification is “Oh Be A Fine Girl/Guy, Kiss Me”. The hotter stars are sometimes referred to as early and the cooler as late. With the discovery of brown dwarfs, objects that form like stars but do not shine through thermonuclear fusion, the system of stellar classification has been expanded to include spectral types L, T, and Y.
Now let's us know about the classification in details.

Today Phil’s explaining the stars and how they can be categorized using their spectra. Together with their distance, this provides a wealth of information about them including their luminosity, size, and temperature. The HR diagram plots stars’ luminosity versus temperature and most stars fall along the main sequence, where they live most of their lives.

The Sun is designated as a "G2V" star. What does that mean?
Featuring Michael Merrifield, Amanda Bauer and Chris Conselise.
Classifying stars - it's the first step we need to start our understanding of stars. Why do we give the star types such weird letters to classify them? Spectroscopic sequence helped analyse the different types in the late 1800's. Featuring the Harvard "computer", Annie Jump Cannon, one of the first woman astronomers, and who came up with the basic classification we use today after simplifying previous classifications.

This video deals with stellar classification. Before going into the merits, however, it is good to say something about spectroscopy, as it is the basis of the same stellar classification.
Spectroscopy is a very powerful method of investigation of the structure of matter which is based on the analysis of the decomposition of the light emitted by it into its fundamental wavelengths.

It is, on the analysis of the electromagnetic spectrum. In astrophysics it is essential to obtain information on the chemical composition and physical conditions of stars.
But what is the electromagnetic spectrum?
• I - almost continuous spectrum with few lines, the most intense of which are due to hydrogen (0 stars the lines of the Balmer series of hydrogen show their maximum. The K line of ionized calcium grows over the whole class.
• II - spectrum similar to the solar one, characterized, next to lines weaker than hydrogen, by a large quantity of metallic lines (sodium, calcium, iron) and by many other thin ones (yellow or orange stars such as Sun, Capella);
• III - spectrum with many thin lines and also with very wide and shaded lines called "bands", with traces of metals and hydrocarbons (orange or red stars such as Betelgeuse, Antares, Mira Ceti);
• IV - spectrum with bands due to carbon, but without metals.
Here is the scheme:
• O - presence of strong absorption lines due to ionized helium. There are absorption lines of ionized helium and hydrogen. The stars belonging to this class have surface temperatures between 28000 and 35000 kelvins (remember that 0 kelvins correspond to -273.15 ° C).
• B - hydrogen lines grow. The three helium lines are at their maximum intensity in B2, they disappear completely in B9. The lines of ionized silicon, oxygen and magnesium are visible. Surface temperatures range from 10,000 Kelvin to 28,000 Kelvin.
• A - in class A0 the lines of the Balmer series of hydrogen show their maximum. The K line of ionized calcium grows over the whole class. Surface temperatures are between 7500 Kelvin and 10000 Kelvin.
• F - hydrogen lines decrease, ionized calcium lines increase. The first lines of metals appear. Stars of this class have surface temperatures between 6000 Kelvin and 7500 Kelvin.
• G - is the class to which the Sun belongs (G2). The lines of hydrogen are further decreasing. The K line of the stock is strengthened. Present numerous lines of neutral metals. Surface temperatures range from 4900 Kelvin to 6000 Kelvin.
• K - the lines of metals grow while those of hydrogen disappear. Surface temperatures are between 3500 Kelvin and 4900 Kelvin.
• M - corresponding to group III of Secchi. The titanium oxide bands, faded towards red, grow for the whole class. Surface temperatures are less than 3500 Kelvin.

Please note that this was designed as an introductory survey of astronomy course, mostly for non-science majors, and does simplify many of the topics accordingly. I encourage people who are just getting into astronomy to use this as a jumping off point for more in depth studies. I've tried to edit out specific references to my course (regarding assignments, tests, etc.) but I might have missed some. Finally, scientific fields are constantly advancing, with new data and studies resulting in our ideas being continually improved. This means some of the ideas presented here may soon be out of date, so I again encourage people to continue to investigate whichever topics are of particular interest to you.

Hungarian State Railways are SOOO Clean and Nice!! WOW! - Hungary - ECTV
Hungarian State Railways (Hungarian: Magyar Államvasutak, MÁV) is the Hungarian national railway company, with divisions "MÁV START Zrt." (passenger transport), "MÁV-Gépészet Zrt." (maintenance), "MÁV-Trakció Zrt." and "MÁV Cargo Zrt" (freight transport).[1] The head office is in Budapest.[2] Construction of Hungary's first railway line began in the second half of 1844. The first steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. This date is regarded as the birth date of the Hungarian railways. The Romantic poet Sándor Petőfi rode on the first train and wrote a poem predicting that rails would connect Hungary like blood vessels in the human body. After the failed revolution, the existing lines were nationalized by the Austrian State and new lines were built. ...

The rail line along the south shore of Lake Balaton was built in 1861 as the Budapest – Székesfehérvár – Nagykanizsa railway. Within the Kingdom of Hungary, it was a main line to Adriatic ports. Its current status is an international route to Slovenia and Croatia, but with many intermediate stations, serving the tourist resorts along the lake shore.
CORRECTION:
the line I marked as going to Kaposvar at 48:45 is the freight-only branch to Mesztegnyo and Somogyszob. The Kaposvar line leaves from Fonyod and can be seen peeling away from the mainline at 1:04:34. I am sorry for the mistake i made.

In this video you can enjoy the cab ride - train drivers' view on Hungarian State Railways (MÁV) train between the Nagykanizsa and Siófok Balaton on the line Budapest – Nagykanizsa – Murakeresztúr line 30 (MÁV) in 4K/60 frames per second. Maximum speed is 120 km/h.
The Budapest–Murakeresztúr railway is a cca. 235-kilometre long railway line in Hungary that connects the Hungarian capital city Budapest with Nagykanizsa and Murakeresztúr. South of Murakeresztúr, the railway connects to the Croatian railway system, specifically the M501 railway serving Čakovec. The M501 connects to the Slovene railways at Središče ob Dravi, extending to Pragersko, while the R201 line branching off in Čakovec serves Varaždin. The line is part of the Pan-European Corridor V.
The rail line along the south shore of Lake Balaton was built in 1861 as the Budapest – Székesfehérvár – Nagykanizsa railway. Within the Kingdom of Hungary, it was a main line to Adriatic ports. Its current status is an international route to Slovenia and Croatia, but with many intermediate stations, serving the tourist resorts along the lake shore.
CORRECTION:
the line I marked as going to Kaposvar at 48:45 is the freight-only branch to Mesztegnyo and Somogyszob. The Kaposvar line leaves from Fonyod and can be seen peeling away from the mainline at 1:04:34. I am sorry for the mistake i made.

Hungarian State Railways (Hungarian: Magyar Államvasutak, MÁV) is the Hungarian national railway company, with divisions "MÁV START Zrt." (passenger transport), "MÁV-Gépészet Zrt." (maintenance), "MÁV-Trakció Zrt." and "MÁV Cargo Zrt" (freight transport).[1] The head office is in Budapest.[2]
Construction of Hungary's first railway line began in the second half of 1844. The first steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. This date is regarded as the birth date of the Hungarian railways. The Romantic poet Sándor Petőfi rode on the first train and wrote a poem predicting that rails would connect Hungary like blood vessels in the human body.
After the failed revolution, the existing lines were nationalized by the Austrian State and new lines were built. As a result of the Austro-Sardinian War in the late 1850s, all these lines were sold to Austrian private companies. During this time the company of Ábrahám Ganz invented a method of "crust-casting" to produce cheap yet sturdy iron railway wheels, which greatly contributed to railway development in Central Europe.
Following the Austro-Hungarian Compromise of 1867 that created the Dual Monarchy of Austria-Hungary, transport issues became the responsibility of the Hungarian Government, which also inherited the duty to support local railway companies. This came at a considerable cost: in 1874 8% of the annual budget went to railway company subsidies. This led the Hungarian Parliament to consider founding a State Railway. The goal was to take over and operate the Hungarian main lines. The branch lines were constructed by private companies. When the law in 1884 provided a simplified way to create railway companies many small branch line companies were founded. These, however, usually only constructed the lines, then made a contract with MÁV to operate them. Thus they also owned no locomotives or other rolling stock. MÁV made a contract only if the line, its equipment and buildings were constructed to MÁV standards. This helped to build standard station buildings, sheds, and accessories, all to the MÁV rules.
Because of relatively high prices the traffic density was considerably lower in Hungary than in other countries. To change this the Interior Minister, Gábor Baross, introduced the zone tariff system in 1889. This system resulted in lower prices for passenger trips and goods transport but it induced a rapid increase in both and so higher overall profits. In 1891 the Hungarian lines of the StEG were bought by the Hungarian State directly from the French owners and became MÁV lines.
In 1890 most large private railway companies were nationalized as a consequence of their poor management, except the strong Austrian-owned Kaschau-Oderberg Railway (KsOd) and the Austrian-Hungarian Southern Railway (SB/DV). They also joined the zone tariff system, and remained successful until the end of World War I when Austria-Hungary collapsed.
By 1910 MÁV had become one of the largest European railway companies, in terms of both its network and its finances. Its profitability, however, always lagged most Western European companies, be they publicly or privately owned. The Hungarian railway infrastructure was largely completed in these years, with a topology centred on Budapest that still remains.
By 1910, the total length of the rail networks of the Hungarian Kingdom reached 22,869 kilometres (14,210 miles), the Hungarian network linked more than 1,490 settlements. Nearly half (52%) of the Austro-Hungarian Empire's railways were built in Hungary, thus the railroad density there became higher than that of Cisleithania. This has ranked Hungarian railways the 6th most dense in the world (ahead of countries as Germany or France).[3]
In 1911 a new locomotive numbering system was introduced which was used until the beginning of the 21st century and is still in use for motive power purchased before then. The notation specifies the number of driven axles and the maximum axle load of the locomotive.
The Hungarian Locomotive (engines and wagons bridge and iron structures) factories
Despite the Hungarian factories were independent companies, the largest suppliers of MÁV were the MÁVAG company in Budapest (steam engines and wagons) and the Ganz company in Budapest (steam engines, wagons, the production of electric locomotives and electric trams started from 1894).[4] and the RÁBA Company in Győr.

So we have made it through the dark ages, and are now a few hundred million years into the lifetime of the universe. There are plenty of stars all over the place, but are they all the same? How can we classify stars? Let's go through the basics of the Harvard System, and then take a look at something called a Hertzsprung-Russell diagram.

We have all heard about the stars and witnessed there beauty in the night sky since our childhood. But Have you ever heard about Stellar Classification of Stars? If your answer is no, then you have landed at the right place because this video will touch the bottom of the topic. Before going too deep first, let us understand what exactly we mean by Stellar Classification of Stars! In astronomy, Stellar Classification is the classification of stars based on their spectral characteristics i.e. relation between wavelength and some other variables. Stellar classification, scheme for assigning stars to types according to their temperatures as estimated from their spectra.

For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space . A star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. When the stellar core is sufficiently dense, hydrogen becomes steadily converted into helium through nuclear fusion, releasing energy in the process. According to the latest data, the observable universe contains 1×1024 stars. The nearest one to our planet is our Sun. Scientists have studied stars for quiet a time now and divided them on them on the basis of their age and temperature. We will discuss one such classification today, which is the stellar classification of stars. Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. We all see the stars twinkling but have you ever wondered how do stars twinkle? To answer this, let us go back to our school days where we were taught refraction of lights. Twinkling of stars is caused by the passing of light through different layers of a tempestuous atmosphere. But in real the stars don't twinkle, they only appear as such because of the interaction between our eyes, stars and Earth's atmosphere. The formation of a star is not a quick process, it takes around a million of years to form a star from an accumulation of gas and dust which collapses due to gravity in its nebulae. Our universe has nebulas, in which new stars are being formed all the time. Though we haven’t observed much of these stars present in our infinite universe but those which are observed give a very good idea of their composition and properties.
Now let us go back to the base of the topic Stellar Classification. It is a scheme assigning stars their type on the basis of their temperatures as calculated from their spectra. The classification of temperature is done on the basis of Wien's Law regarding black body radiation. The universally accepted system of stellar classification is a combination of two schemes, the Harvard system, which is based on the star's surface temperature, and the MK i.e. Morgan Keenan system, which is based on the stars luminosity. The MK also called Yerkes system, is the work of the American astronomers W.W. Morgan, P.C. Keenan, and few others. It is based on two sets of parameters-a refined version of the Harvard O-M scale, and a luminosity scale of grades I-for super-giants, II-bright giants, III-normal giants, IV-sub-giants, and V-main sequence, or dwarf, stars; further specifications may be used, such as a grade Ia for bright super-giants and grades VI and VII for sub-dwarfs and white dwarfs, respectively. In the Harvard system the stars are classified on as the hottest to coolest using letters such as O, B, A, F, G, K, M where O is the hottest(25,000 K) and blue in colour and M is the coolest (3,500 K) star which is red in colour. The letters are further subdivided from hot to cool. An adapted and famous mnemonic for memorising this sequence of stellar classification is “Oh Be A Fine Girl/Guy, Kiss Me”. The hotter stars are sometimes referred to as early and the cooler as late. With the discovery of brown dwarfs, objects that form like stars but do not shine through thermonuclear fusion, the system of stellar classification has been expanded to include spectral types L, T, and Y.
Now let's us know about the classification in details.

Today Phil’s explaining the stars and how they can be categorized using their spectra. Together with their distance, this provides a wealth of information about them including their luminosity, size, and temperature. The HR diagram plots stars’ luminosity versus temperature and most stars fall along the main sequence, where they live most of their lives.

The Sun is designated as a "G2V" star. What does that mean?
Featuring Michael Merrifield, Amanda Bauer and Chris Conselise.
Classifying stars - it's the first step we need to start our understanding of stars. Why do we give the star types such weird letters to classify them? Spectroscopic sequence helped analyse the different types in the late 1800's. Featuring the Harvard "computer", Annie Jump Cannon, one of the first woman astronomers, and who came up with the basic classification we use today after simplifying previous classifications.

This video deals with stellar classification. Before going into the merits, however, it is good to say something about spectroscopy, as it is the basis of the same stellar classification.
Spectroscopy is a very powerful method of investigation of the structure of matter which is based on the analysis of the decomposition of the light emitted by it into its fundamental wavelengths.

It is, on the analysis of the electromagnetic spectrum. In astrophysics it is essential to obtain information on the chemical composition and physical conditions of stars.
But what is the electromagnetic spectrum?
• I - almost continuous spectrum with few lines, the most intense of which are due to hydrogen (0 stars the lines of the Balmer series of hydrogen show their maximum. The K line of ionized calcium grows over the whole class.
• II - spectrum similar to the solar one, characterized, next to lines weaker than hydrogen, by a large quantity of metallic lines (sodium, calcium, iron) and by many other thin ones (yellow or orange stars such as Sun, Capella);
• III - spectrum with many thin lines and also with very wide and shaded lines called "bands", with traces of metals and hydrocarbons (orange or red stars such as Betelgeuse, Antares, Mira Ceti);
• IV - spectrum with bands due to carbon, but without metals.
Here is the scheme:
• O - presence of strong absorption lines due to ionized helium. There are absorption lines of ionized helium and hydrogen. The stars belonging to this class have surface temperatures between 28000 and 35000 kelvins (remember that 0 kelvins correspond to -273.15 ° C).
• B - hydrogen lines grow. The three helium lines are at their maximum intensity in B2, they disappear completely in B9. The lines of ionized silicon, oxygen and magnesium are visible. Surface temperatures range from 10,000 Kelvin to 28,000 Kelvin.
• A - in class A0 the lines of the Balmer series of hydrogen show their maximum. The K line of ionized calcium grows over the whole class. Surface temperatures are between 7500 Kelvin and 10000 Kelvin.
• F - hydrogen lines decrease, ionized calcium lines increase. The first lines of metals appear. Stars of this class have surface temperatures between 6000 Kelvin and 7500 Kelvin.
• G - is the class to which the Sun belongs (G2). The lines of hydrogen are further decreasing. The K line of the stock is strengthened. Present numerous lines of neutral metals. Surface temperatures range from 4900 Kelvin to 6000 Kelvin.
• K - the lines of metals grow while those of hydrogen disappear. Surface temperatures are between 3500 Kelvin and 4900 Kelvin.
• M - corresponding to group III of Secchi. The titanium oxide bands, faded towards red, grow for the whole class. Surface temperatures are less than 3500 Kelvin.

Please note that this was designed as an introductory survey of astronomy course, mostly for non-science majors, and does simplify many of the topics accordingly. I encourage people who are just getting into astronomy to use this as a jumping off point for more in depth studies. I've tried to edit out specific references to my course (regarding assignments, tests, etc.) but I might have missed some. Finally, scientific fields are constantly advancing, with new data and studies resulting in our ideas being continually improved. This means some of the ideas presented here may soon be out of date, so I again encourage people to continue to investigate whichever topics are of particular interest to you.

9K114 Shturm
9K114 Shturm (Russian: 9К114 «Штурм»- "shturm" means storm (assault) in English) is a SACLOS radio guided anti-tank missile system of the Soviet Union. Its GRAU designation is 9K114. Its NATO reporting name is AT-6 Spiral. The missile itself is known as the 9M114 Kokon (Cocoon).
Development
The missile was developed by the Kolomna Machine Design Bureau, which was also responsible for the 3M6 Shmel and 9M14 Malyutka. Work on the missile began in 1967, with the hope of using the missile on Mi-24s. However, delays forced the design of an upgraded Falanga system (9M17 Skorpion) using SACLOS guidance as a stopgap. Testing of the missile was completed in 1974, and it was accepted into service in 1976. The missile has no direct western counterpart, though, in role, it is closest to the AGM-114 Hellfire, and in guidance method, to the MGM-18 Lacrosse.
It was originally given the NATO designation AS-8, before being redesignated as AT-6.
Description
The missile can be deployed on a variety of platforms, including the Mi-24V and from 1979-onwards the MT-LB based 9P149 tank destroyer. There is also a shipborne version of the missile, with the launcher holding six missiles.

In this video you can enjoy the cab ride - train drivers' view on Hungarian State Railways (MÁV) train between the Nagykanizsa and Siófok Balaton on the line Budapest – Nagykanizsa – Murakeresztúr line 30 (MÁV) in 4K/60 frames per second. Maximum speed is 120 km/h.
The Budapest–Murakeresztúr railway is a cca. 235-kilometre long railway line in Hungary that connects the Hungarian capital city Budapest with Nagykanizsa and Murakeresztúr. South of Murakeresztúr, the railway connects to the Croatian railway system, specifically the M501 railway serving Čakovec. The M501 connects to the Slovene railways at Središče ob Dravi, extending to Pragersko, while the R201 line branching off in Čakovec serves Varaždin. The line is part of the Pan-European Corridor V.
The rail line along the south shore of Lake Balaton was built in 1861 as the Budapest – Székesfehérvár – Nagykanizsa railway. Within the Kingdom of Hungary, it was a main line to Adriatic ports. Its current status is an international route to Slovenia and Croatia, but with many intermediate stations, serving the tourist resorts along the lake shore.
CORRECTION:
the line I marked as going to Kaposvar at 48:45 is the freight-only branch to Mesztegnyo and Somogyszob. The Kaposvar line leaves from Fonyod and can be seen peeling away from the mainline at 1:04:34. I am sorry for the mistake i made.

Hungarian State Railways (Hungarian: Magyar Államvasutak, MÁV) is the Hungarian national railway company, with divisions "MÁV START Zrt." (passenger transport), "MÁV-Gépészet Zrt." (maintenance), "MÁV-Trakció Zrt." and "MÁV Cargo Zrt" (freight transport).[1] The head office is in Budapest.[2]
Construction of Hungary's first railway line began in the second half of 1844. The first steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. This date is regarded as the birth date of the Hungarian railways. The Romantic poet Sándor Petőfi rode on the first train and wrote a poem predicting that rails would connect Hungary like blood vessels in the human body.
After the failed revolution, the existing lines were nationalized by the Austrian State and new lines were built. As a result of the Austro-Sardinian War in the late 1850s, all these lines were sold to Austrian private companies. During this time the company of Ábrahám Ganz invented a method of "crust-casting" to produce cheap yet sturdy iron railway wheels, which greatly contributed to railway development in Central Europe.
Following the Austro-Hungarian Compromise of 1867 that created the Dual Monarchy of Austria-Hungary, transport issues became the responsibility of the Hungarian Government, which also inherited the duty to support local railway companies. This came at a considerable cost: in 1874 8% of the annual budget went to railway company subsidies. This led the Hungarian Parliament to consider founding a State Railway. The goal was to take over and operate the Hungarian main lines. The branch lines were constructed by private companies. When the law in 1884 provided a simplified way to create railway companies many small branch line companies were founded. These, however, usually only constructed the lines, then made a contract with MÁV to operate them. Thus they also owned no locomotives or other rolling stock. MÁV made a contract only if the line, its equipment and buildings were constructed to MÁV standards. This helped to build standard station buildings, sheds, and accessories, all to the MÁV rules.
Because of relatively high prices the traffic density was considerably lower in Hungary than in other countries. To change this the Interior Minister, Gábor Baross, introduced the zone tariff system in 1889. This system resulted in lower prices for passenger trips and goods transport but it induced a rapid increase in both and so higher overall profits. In 1891 the Hungarian lines of the StEG were bought by the Hungarian State directly from the French owners and became MÁV lines.
In 1890 most large private railway companies were nationalized as a consequence of their poor management, except the strong Austrian-owned Kaschau-Oderberg Railway (KsOd) and the Austrian-Hungarian Southern Railway (SB/DV). They also joined the zone tariff system, and remained successful until the end of World War I when Austria-Hungary collapsed.
By 1910 MÁV had become one of the largest European railway companies, in terms of both its network and its finances. Its profitability, however, always lagged most Western European companies, be they publicly or privately owned. The Hungarian railway infrastructure was largely completed in these years, with a topology centred on Budapest that still remains.
By 1910, the total length of the rail networks of the Hungarian Kingdom reached 22,869 kilometres (14,210 miles), the Hungarian network linked more than 1,490 settlements. Nearly half (52%) of the Austro-Hungarian Empire's railways were built in Hungary, thus the railroad density there became higher than that of Cisleithania. This has ranked Hungarian railways the 6th most dense in the world (ahead of countries as Germany or France).[3]
In 1911 a new locomotive numbering system was introduced which was used until the beginning of the 21st century and is still in use for motive power purchased before then. The notation specifies the number of driven axles and the maximum axle load of the locomotive.
The Hungarian Locomotive (engines and wagons bridge and iron structures) factories
Despite the Hungarian factories were independent companies, the largest suppliers of MÁV were the MÁVAG company in Budapest (steam engines and wagons) and the Ganz company in Budapest (steam engines, wagons, the production of electric locomotives and electric trams started from 1894).[4] and the RÁBA Company in Győr.
