Scientific paper

We present CCD UBVI observations obtained in the field of the previously unstudied northern open clusters NGC 133 and NGC 1348. We argue that NGC 133 is a heavily contaminated cluster, for which we identify 13 candidate members down to V=14.50mag on the basis of the position in the two-color Diagram. Membership has been checked against proper motions from Tycho 2, whenever available. The cluster turns out to have a reddening E(B-V)=0.60+/-0.10mag, to be 630+/-150pc distant from the Sun, and to have an age less than 10Myrs. NGC 1348 is a more reddened clusters (E(B-V)=0.85+/-0.15mag) for which we isolate 20 members. The cluster lies at a distance of 1.9+/-0.5kpc away from the Sun, and has an age greater than 50Myrs. Observations were carried out with the AFOSC camera at the 1.82m Copernico telescope of Cima Ekar (Asiago, Italy), in the photometric night of December 18, 2001. (2 data files).
