NGC 4441
NGC 4441 is a peculiar lenticular galaxy in the constellation of Draco. Its velocity with respect to the cosmic microwave background is, which corresponds to a Hubble distance of. However, two non-redshift measurements give a much closer mean distance of. It was discovered by German-British astronomer William Herschel on 20 March 1790.
According to Abraham Mahtessian, NGC 4441 is part of the NGC 4125 group, which has at least 12 members. The other galaxies in this group are NGC 3796, NGC 3945, NGC 4036, NGC 4041, NGC 4081, NGC 4125, NGC 4205, NGC 4391, IC 758, UGC 7009, and UGC 7020A.
Supernovae
Two supernovae have been observed in NGC 4441:SN 2019yvq was discovered by Kōichi Itagaki on 28 December 2019. It was originally classified as a Type [Ib and Ic supernovae|TypeIb/c], but later analysis concluded it to be a peculiar Type Ia, similar to SN2002es. It was extremely bright in the ultraviolet but otherwise underluminous, and was relatively quickly declining in its brightness.SN 2025aecv was discovered by Asteroid Terrestrial-impact [Last Alert System|ATLAS] on 18 November 2025.
