NGC 1620 is an intermediate spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 3,455 ± 4 km/s, which corresponds to a Hubble distance of 51.0 ± 3.6 Mpc Mpc (∼166 million light-years).[1] It was discovered by German-British astronomer William Herschel on 1 January 1786.
Two supernovae have been observed in NGC 1620: SN 2009K (type IIb, mag. 14.9)[2] and SN 2023crx (type Ib, mag. 18.6).[3]
