NGC 524 is a lenticular galaxy in the constellation Pisces.[1] It is at a distance of about 90 million light-years away from Earth. In the central bulge of the galaxy is visible gas forming a spiral structure.[3] It is the largest galaxy in the small NGC 524 group of galaxies, which is associated with NGC 488 and its group.[4] It was discovered by William Herschel on 4 September 1786.[5]

Observation

[edit]

On 4 May 1985 (the May 1985 lunar eclipse) it was occulted by the Moon during a Total Lunar Eclipse over South Africa and Antarctica.[6]: 160 

Supernovae

[edit]

Two supernovae have been observed in the galaxy:

  • SN 2000cx (Type Ia-pec, mag. 14.5) was discovered by the Lick Observatory Supernova Search (LOSS) on 17 July 2000.[7][8] This supernova reached magnitue 13.1, and was the brightest observed in the year 2000.[9]
  • SN 2008Q (Type Ia, mag. 16.5) was discovered by Giancarlo Cortini on 26 January 2008.[10][11]
