We have obtained CCD UBVI_(KC) photometry for NGC 2309, a relatively poor open cluster (OC) projected onto a rich star field in Monoceros. Prob- able cluster members have been identified for the first time from sound pho- tometric 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).
