NGC 523, also known as Arp 158, from the ARP catalog is a spiral galaxy located in the constellation Andromeda. [1] It was discovered separately by William Herschel on 13 September 1784, and by Heinrich d'Arrest on 13 August 1862. d'Arrest's discovery was listed as NGC 523, while Herschel's was listed as NGC 537; the two are one and the same.

2023年10月21日 · Historical Identification: Per Dreyer, NGC 537 (= GC 319 = WH III 170, 1860 RA 01 18 27, NPD 56 39.1) is "stellar (perhaps = GC 306?)", GC 306 being NGC 523, so Dreyer's suggestion of the duplicate entry turned out to be correct. Physical Information: Given the duplicate entry, see NGC 523 for anything else.

Arp 158 is NGC 523/537. It is a very strange galaxy. Arp put it in his category: Galaxies (not classifiable as S or E); Disturbed with interior absorption. I'm not sure what that means. Centaurus A (NGC 5128) also falls in this category though I won't be imaging it of course as it is always below my horizon.
