NGC 2315
Galaxy in the constellation Lynx
From Wikipedia, the free encyclopedia
NGC 2315 is a lenticular galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 6,369±60 km/s, which corresponds to a Hubble distance of 306.4 ± 21.8 Mly (93.94 ± 6.69 Mpc).[1] It was discovered by British astronomer John Herschel on 16 February 1831.[2]

NGC 2315 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[3] It also has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]

Supernova
One supernova has been observed in NGC 2315:
- SN 2011ay (Type Iax, mag. 17.8) was discovered by the Lick Observatory Supernova Search (LOSS) on 18 March 2011.[8][9] It was initially classified as Type Ia-pec, but later anaylsis concluded that it was Type Iax.[10]
