Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "Cluster VI; F, rich, highly compressed; consists of pL and eS stars; fig oblong; 10' long, 7' broad; place that of chief star 9th mag." On a second occassion he called it "Cluster VIII class; 8' long, 5' broad; stars 12th and 13th mag. (NB -- it is evident that in this obs. probably from defective weather, the eS stars of this cluster were not seen.)"

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a open cluster. Their coded description reads DOUBTFUL R.
