Heinrich d'Arrest discovered NGC 2807 on 17 Feb 1863 while observing NGC 2809. He noted h578 NGC 2809] follows by 7 seconds in time and 115" north. His position (measured on 4 nights) and description matches MCG +03-24-031 = PGC 26213. Several sources such as RNGC, MCG, Uranometria 2000.0 and Deep Sky Field Guide misidentify MCG +03-24-030 (just 50" WSW) as NGC 2807. d'Arrest did not mention this galaxy. UGC and CGCG have the correct identification (noted as a double system). Megastar mislabels NGC 2807 as NGC 2806.

400/500mm - 17.5" (3/12/94): very faint, very small, slightly elongated NNW-SSE, weakly concentrated. Located 2.5' SSW of NGC 2809 in a group with a mag 10 star 3.3' S. At moments, an extremely faint companion possibly elongated E-W is barely visible just west of the south edge (separation 49"). This fainter component of the double system NGC 2807 is incorrectly identified as NGC 2806 in the RNGC, MCG, U2000.
