"Except for the two bright red stars (1 & 3) the determination of membership for this cluster poses no special problem ... We derive ... d = 1.05kpc, earliest Sp = B3; 6' diameter; 22 members studied."

Contemporary observations

1998-01-24/25, 6-inch f/8.6 Newtonian, Stellenbosch Rifle Range site. Cluster south-east of Epsilon Crucis. Least impressive cluster of the evening. With K12.5mm at 104x it is just two stars arranged almost north-south.

A much finer view is to be had just 10 arcmni due west, where there is a neat clump of 20 large and small stars in an area 6 arcmin across.


1997-03-24, Monday. Jonkershoek. 11x80 tripod. Full Moon. Not found.


1997-09-20, Sutherland (Karoo), SAAO plateau. 11x80 tripod-mounted binoculars. Skies excellent. Position accuratley verified; nothing seen.

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (95x, 218x)

In combination with various magnitude stars this cluster show off a sort of X formation. Very tight string of faint stars running out to the SE. The brightest row of 7 stars situated in a E to W direction. Fainter stars sweeping out north complete the shape of this grouping.
