NGC 5371 is a face-on spiral galaxy in the northern constellation Canes Venatici. It was discovered on January 14, 1788 by German-British astronomer William Herschel. The nearby NGC 5390 appears to be a duplicate entry for NGC 5371, since there is nothing at the former's position.[1] NGC 5371 has an apparent magnitude of 11.3 and an angular size of Script error: No such module "val"..[2] It is located at a distance of Script error: No such module "convert". from the Milky Way,[3] and is receding with a heliocentric radial velocity of 2,552 km/s. The galaxy appears to be weakly interacting with the nearby, equidistant Hickson 68 group of galaxies, and thus may be a member.[4] Collectively, they are sometimes dubbed the Big Lick galaxy group, after the city of Roanoke, Virginia.[5]
The morphological classification of NGC 5371 in the De Vaucouleurs system is SAB(rs)bc,[2] indicating a weakly barred spiral galaxy (SAB) with a transitional inner ring structure (rs), and moderately wound spiral arms (bc). The galactic plane is inclined at an angle of Script error: No such module "val". to the plane of the sky, with the major axis oriented along a position angle of Script error: No such module "val"..[6] This is classified as a LINER-type galaxy and may be in a post-starburst phase. There is an extended or double source of X-ray emission.[7]
Two supernovae have been observed in NGC 5371. Type II-L supernova SN 1994Y was spotted on August 19, 1994, reaching peak B magnitude of 14.2 on August 30.[8] Type IIb supernova SN 2020bio was discovered January 29, 2020. The progenitor may have undergone extensive mass loss, shedding nearly all of its hydrogen envelope.[9]
