NGC 1285 is a barred spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 5081 ± 12 km/s, which corresponds to a Hubble distance of 244.4 ± 17.1 Mly (74.94 ± 5.25 Mpc).[1] However, three non-redshift measurements give a distance of 180.47 ± 3.24 Mly (55.333 ± 0.994 Mpc).[2] It was discovered by Heinrich Louis d'Arrest on 28 October 1865.[3]
Supernovae
[edit]Three supernovae have been observed in NGC 1285. SN 2004F (type II, mag. 17.8) was discovered by the Lick Observatory Supernova Survey on 16 January 2004.[4] SN 2013el (type Ib, mag. 15.5) was discovered by Stu Parker on 11 July 2013.[5] SN 2017fvf (type IIP, mag. 17.81) was discovered by the Gaia Photometric Science Alerts programme on 30 July 2017.[6]
