NGC 337 is a barred spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is 1,331±22 km/s, which corresponds to a Hubble distance of 64.0 ± 4.6 Mly (19.63 ± 1.41 Mpc).[1] Additionally, 20 non-redshift measurements give a similar distance of 63.11 ± 1.81 Mly (19.350 ± 0.556 Mpc).[2] It was discovered on September 10, 1785 by German-British astronomer William Herschel.[3] It was described by John Dreyer as "pretty faint, large, extended, gradually a little brighter middle, 10th magnitude star 21 seconds of time to the east."[3]
Supernovae
Two supernovae have been observed in NGC 337:
- SN 2011dq (type II, mag. 16.3) was discovered by Berto Monard on May 15, 2011.[4][5]
- SN 2014cx (type II-P, mag. 15.6) was discovered by Kōichi Itagaki on September 2, 2014.[6][7]
NGC 337 Group
NGC 337 is the largest and brightest galaxy in the NGC 337 Group (also known as LGG 15). The group includes at least three other galaxies: NGC 274, NGC 275, and NGC 298.[8]
