Photoelectric UBV observations of 120 stars in the young open cluster
Trumpler 37 are presented, primarily in the magnitude range 10.0 - 13.5.
An analysis of the color-magnitude diagram of the cluster yields an age
of 6.7 million yr and reveals the presence of a number of possible
pre-main-sequence stars in the cluster.
