George Johnstone Stoney or Bindon Stoney, LdR's assistants, discovered NGC 7631 on 30 Aug 1851. He noted "12' following h's second nebula [NGC 7626] is another E preceding and following, F, light unequal." Heinrich d'Arrest independently discovered this galaxy on 21 Sep 1862 and made a total of 6 observations (noting the equivalence of the two GC entries from LdR and himself).

300/350mm - 13" (11/5/83): faint, weak concentration, elongated ~E-W.

400/500mm - 17.5" (9/14/85): fairly faint, fairly small, slightly elongated E-W, gradually brightens but no nucleus, fainter extensions. Located 11.0' E of NGC 7626 in the Pegasus I cluster.
