NGC 4523 is a Magellanic spiral galaxy located about 35 to 50 million light-years away[3] in the constellation Coma Berenices.[4] It was discovered by astronomer Heinrich d'Arrest on April 19, 1865.[5] NGC 4523 is a member of the Virgo Cluster.[6][7] A distance of (13 ± 2 Mpc) for NGC 4523 was derived from using yellow supergiants in the galaxy as standard candles.[6]
On December 23, 1999, a Type II supernova designated as SN 1999gq was detected in NGC 4523.[8][9]
