Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, vS, R, glbM, resolvable, 15 arcseconds." On a second occassion he called it "pB, vS, R, vlbM, 15 arcseconds, resolvable." His third observation was recorded as "an extremely small bright knot of the Nubec. Min. 15 arcseconds diameter." His fourth record reads "pB, vS, R, 12 arcseconds, resolvable. Situate at the upper limit of the nubecula which here is starry. At the other it is nebulous."

Describes it as a blue cluster, noting the presence of nebulosity as well as very bright blue stars, probably blue supergiants. He notes that it is concentrated towards the centre and exhibits emission nebulosity.
Lindsay ("Clusters in the Small Magellanic Cloud", Irish Astronomical Journal, Vol. 4, 1956) classifies it as an open cluster.
1994-12-04, Die Boord, 6-inch f/8.6 Newtonian. 108x shows a globular cluster like object: an out of focus star. It is very faint but easy once found. Makes a nice triangle with two bright field stars. Lies near NGC 306.
11x80: 1997-10-09, 02:30, Jonkershoek, seeing 3, transparency 3, darkness 3 "Perhaps seen as a slightly more dense gathering in the northern edge of the SMC body - or is it just a small star?"
The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag cluster+nebulosity in the SMC.
