UGC 4904
UGC 4904 is a barred spiral galaxy in the constellation Lynx. Its velocity with respect to the cosmic microwave background is 1880 ± 15 km/s, which corresponds to a Hubble distance of 90.5 ± 6.4 Mly (27.74 ± 1.96 Mpc). The first known reference to this galaxy comes from Part 2 of the Morphological Catalogue of Galaxies, published in 1964, where it is listed as MCG +07-19-054.
On October 20, 2004, a supernova impostor was observed by Japanese amateur astronomer Kōichi Itagaki within the galaxy. This same star may have transitioned from a luminous blue variable star to a Wolf–Rayet star shortly before it was observed as blowing up as supernova SN 2006jc (type Ibn, mag. 13.8) on October 11, 2006.
