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 "middle of a small group of bright stars." On a second occassion he called it "cheif star 9th mag of a small bright clustering group of from 12 to 20 pretty large stars, with stragglers."

"A well-defined cluster sequence is visible" in the two-colour and both colour-magnitude diagrams. ... d = 0.91 kpc and earliest Sp = B1."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 7.0 mag open cluster.

Contemporary observations

Auke Slotegraaf

1991

This cluster lies a few degrees south of Mu Normae. Between this cluster and star lies an interesting T-shaped asterism, with the cross-bar of the T extending north south. The cluster's location is marked by a double star, but only uncertain, subjective nebulosity can be seen here with the 11x80's Look for a nice chain of stars due east of the clusterdouble.
