We have obtained CCD UBVI$_{KC}$ photometry for NGC,2309, a relatively poor open cluster (OC) projected onto a rich star field in Monoceros. Probable cluster members have been identified for the first time from sound photometric criteria. We have derived the angular radius and the fundamental cluster parameters. The resulting reddening and distance values place this object among the relatively most reddened and distant known OCs projected towards the direction of NGC,2309. A detailed version of this work can be seen in PASP, 122, 288 (2010).
