NGC 5371

The morphological classification of NGC 5371 in the De Vaucouleurs system is SAB(rs)bc, 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 45°±5° to the plane of the sky, with the major axis oriented along a position angle of 195°±3°. 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.

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. 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.
