NGC 4441
Galaxy in the constellation Dorado
From Wikipedia, the free encyclopedia
NGC 4441 is a peculiar lenticular galaxy in the constellation of Draco. Its velocity with respect to the cosmic microwave background is 2,830±8 km/s, which corresponds to a Hubble distance of 136.1 ± 9.5 Mly (41.74 ± 2.92 Mpc).[1] However, two non-redshift measurements give a much closer mean distance of 62.46 ± 0.49 Mly (19.150 ± 0.150 Mpc).[2] It was discovered by German-British astronomer William Herschel on 20 March 1790.[3]

Supernovae
Two supernovae have been observed in NGC 4441:
- SN 2019yvq (Type Ia, mag. 16.7) was discovered by Kōichi Itagaki on 28 December 2019.[5] It was originally classified as a Type Ib/c, but later analysis concluded it to be a peculiar Type Ia, similar to SN 2002es.[6] It was extremely bright in the ultraviolet but otherwise underluminous, and was relatively quickly declining in its brightness.[6]
- SN 2025aecv (Type II, mag. 17.589) was discovered by ATLAS on 18 November 2025.[7]
