The open cluster NGC 2527.
Abstract
Photographic magnitudes on the UBV system based on a photoelectric sequence have been determined for stars in NGC 2527, designed as an open cluster. Spectral classes have been determined for the brightest stars from slit spectra and objective prism plates. NGC 2527 seems to consist of about 25 stars, all of them brighter than V 1 3rn. The brightest stars show spectral classes A2 - A8, and NGC 2527 is likely to be a real cluster. The colour excess, , in front of the cluster is about 0 .1 and the distance 550 pc. Key words: open cluster - UBV-photometry
