NGC 2309: A relatively young open cluster projected onto a random stellar concentration
We have obtained CCD UBV IKC photometry down to V ∼ 22:0 for the open cluster NGC 2309 and its surrounding field. Twenty three probable cluster members have been identified for the first time on the basis of sound photometric criteria. Because NGC 2309 is a relatively poor cluster projected onto a r...
