NGC 1233 (also listed as NGC 1235) is a spiral galaxy in the constellation of Perseus. Its velocity with respect to the cosmic microwave background is 4218 ± 14 km/s, which corresponds to a Hubble distance of 202.9 ± 14.2 Mly (62.22 ± 4.36 Mpc).[1] In addition, three non redshift measurements give a distance of 211.35 ± 2.14 Mly (64.800 ± 0.656 Mpc).[2] The galaxy was discovered by French astronomer Édouard Stephan on 10 December 1871.[3] It is also thought to have been observed by Lewis Swift on 21 October 1886, and later listed as NGC 1235.[4]
