Abstract
Proper motions and photographic photometry have been derived for nearl y 600 stars with 7.5 < V< 15.5 in the region of the very young open cl usters Tr 14, Tr 16, and Cr 232 based on 26 plates dating from 1893 to 1990. Cluster membership probabilities have been derived from the pro per motions and color-magnitude diagrams of probable members of each c luster are presented. In contrast to a few of the previous studies we find all three clusters to lie at the same distance.
