NGC 523, also known as Arp 158 from the ARP catalog, is a spiral galaxy located in the constellation Andromeda.[1] It was discovered by German-British astronomer William Herschel on 13 September 1784. Heinrich d'Arrest rediscovered it on 13 August 1862 and listed it as NGC 523, whereas Herschel's original discovery was listed as NGC 537.[4] John Dreyer noted in the New General Catalogue that NGC 523 is a double nebula.[1]
Supernova
[edit | edit source]One supernova has been observed in NGC 523: SN 2001en (type Ia, mag. 17.5) was discovered by LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches) on 26 September 2001.[5][6][7]
NGC 507 Group
[edit | edit source]NGC 523 is part of the NGC 507 group (also known as LGG 26). This large group includes at least 42 galaxies, of which 21 are in the New General Catalogue and 5 in the Index Catalog. Four members of this group are also Markarian galaxies. The brightest of these galaxies is NGC 507 and the largest is NGC 536.[8]
