Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, vgbM, irregular figure." On a second occasion he called it "The first of an irregular string of nebulae and stars which descends at an angle of about 45 degrees from the centre to the edge of the field (i.e. in a n f direction)." His third observation was recorded as "F, R; the field is full of the nebulous light of the Nubecula Minor."
