On 14 Mar 1831(sweep 333), John Herschel wrote, "pB, pL, R, glbM, 40". In a rich part of the heavens." and measured an accurate position.

300/350mm - 13.1" (1/18/85): fairly faint, nearly round, very weak concentration, low surface brightness. A mag 13.5 star is superimposed at the east edge 30" from center.
