First CCD UBVI photometric analysis of six open cluster candidates

We have obtained CCD UBVIKC photometry down to V ∼ 22 for the open cluster candidates Haffner 3, Haffner 5, NGC 2368, Haffner 25, Hogg 3 and Hogg 4 and their surrounding fields. None of these objects have been photometrically studied so far. Our analysis shows that these stellar groups are not genui...
