Collinder 228 and the η Carinae complex.
Abstract
Photoelectric UBV observations of 99 stars in the region of the open cluster Cr 228 are reported. It is shown that some of them belong to a group situated at a distance of 2500 pc, but some others seem to be related to the complex Tr 14/Tr 16. The former group is nearer and less reddened. Its age is less than 5>c 106 years. A discussion about the star HD 93206 is also given. Key words: open cluster - UB V photometry - colour excess
