NGC 2415 is an irregular galaxy in the constellation of Lynx,[1] near the border with Gemini (some sources claim it is in Gemini[3]). Its velocity with respect to the cosmic microwave background is 3,935±12 km/s, which corresponds to a Hubble distance of 189.3 ± 13.3 Mly (58.04 ± 4.07 Mpc).[2] It was discovered by German-British astronomer William Herschel on 10 March 1790.[4][3]

NGC 2415 group

[edit]

NGC 2415 is the namesake of the NGC 2415 group (also known as LGG 148) which has at least 9 members. The other eight galaxies are NGC 2444, NGC 2445, NGC 2476 [fr], NGC 2493 [fr], NGC 2524 [fr], NGC 2528, UGC 3937 [d], and UGC 3944 [d].[5][6]

Supernovae

[edit]

Two supernovae have been observed in NGC 2415:

  • SN 1998Y (Type II, mag. 18.3) was discovered by the Lick Observatory Supernova Search (LOSS) 16 March 1998.[7][8]
  • SN 2000C (Type Ic, mag. 15.5) was discovered by Steven Foulkes, and independently by Marco Migliardi, on 8 January 2000.[9][10]
