It was discovered by the German-British astronomer William Herschel on March 15, 1784, using his telescope in Slough, England. Classified as a LINER-type Active Galactic Nucleus (AGN), NGC 3817 exhibits low-ionization nuclear emission lines from its core. With an apparent magnitude of 14.4, the galaxy features a faint ring structure and loosely wound spiral arms.[1]
