dc.description.abstract	We present the first CCD photometric observations of the open cluster ocl 630 (NGC 2509) in UBVRI filters. It is a fairly nearby cluster at a distance of 912±15 pc, and is placed in the direction of the Puppis constellation as part of the Orion arm in our Galaxy. The age of this cluster is estimated to be ~8x10 to the power 9 years. This cluster is found to be older than M67, but younger than NGC 188, both of which are well known old clusters. Thus, being an old cluster, it is an unsuitable candidate for tracing the spiral arm of our Galaxy.	en
