NGC 524 is a lenticular galaxy in the constellation Pisces. 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.[2] It is the largest galaxy in the small NGC 524 group of galaxies, which is associated with NGC 488 and its group.[3] It was discovered by William Herschel on 4 September 1786.[4]

Observation

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.[5]: 160 

Supernovae

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.[6][7] This supernova reached magnitue 13.1, and was the brightest observed in the year 2000.[8]
  • SN 2008Q (type Ia, mag. 16.5) was discovered by Giancarlo Cortini on 26 January 2008.[9][10]
