NGC 3437
Galaxy in the constellation Leo
From Wikipedia, the free encyclopedia
NGC 3437 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,597±23 km/s, which corresponds to a Hubble distance of 76.8 ± 5.5 Mly (23.56 ± 1.68 Mpc).[1] Additionally, 17 non-redshift measurements give a similar mean distance of 79.12 ± 2.14 Mly (24.259 ± 0.656 Mpc).[2] It was discovered by German-British astronomer William Herschel on 12 March 1784.[3][4]

Supernova and luminous red nova
One supernova and one luminous red nova have been observed in NGC 3437:
- SN 2004bm (Type Ic, mag. 17.5) was discovered by the Lick Observatory Supernova Search (LOSS) on 25 April 2004.[6][7]
- NGC 3437−2011OT1 (also named PSN J10523453+2256052 and SNhunt31) (Type LRN, mag. 18.4) was discovered by the Catalina Real-time Transient Survey on 10 January 2011.[8] It was initially suspected of being a luminous blue variable, but later analysis concluded that it was a luminous red nova.[9]
