Abstract:
Photoelectric and photographic photometry of twenty-nine stars was done in the field of the open cluster Collinder 97 ≡ OCl 506. Of these stars, a total of twenty-four have been found to be possible members. There is apparently no interstellar extinction in the direction of this cluster. This cluster is situated at a distance of 0.63±0.01 kpc, which is well within the local arm of our Galaxy. The age of this cluster is in the range of 1×108 to 5.9×108yr, which puts it in an older age group. Thus, it cannot be specifically considered as a spiral-arm tracer in the study of our Galaxy.
