Resumen:
We present CCD UBVI$_{KC}$ photometry in the fields of the unstudied open cluster (OC) candidates Haffner,3, Haffner,5, NGC,2368, Haffner,25, Hogg,3 and Hogg,4. Our analysis shows that none of these objects are genuine OCs since no clear main sequences or other typical features can be seen in their colour-magnitude and colour-colour diagrams. Star counts performed within and outside the OC candidate fields not only support these results but also suggest that these objects are not OC remnants. A detailed version of this work can be seen in New Astronomy, 16, 161 (2011).
