NGC 692 is a barred spiral galaxy in the constellation of Phoenix. Its velocity with respect to the cosmic microwave background is 6,088±24 km/s, which corresponds to a Hubble distance of 292.9 ± 20.5 Mly (89.79 ± 6.30 Mpc).[1] It was discovered by British astronomer John Herschel on 2 October 1834.[2]

NGC 692 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.[3][4]

Supernovae

Two supernovae have been observed in NGC 692:

  • SN 2007st (Type Ia, mag. 15.0) was discovered by Berto Monard (it) on 22 December 2007.[5][6]
  • SN 2010aa (Type Ia, mag. 16.4) was discovered by Berto Monard on 9 February 2010.[7][8]
