A photometric study of the two poorly known northern open clusters NGC 133 and NGC 1348 ? , ? ?

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 =14.50 mag 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 ± 0.10 mag, to be 630 ± 150 pc distant from the Sun, and to have an age less than 10 Myrs. NGC 1348 is a more reddened clusters (E(B − V ) = 0.85± 0.15 mag) for which we isolate 20 members. The cluster lies at a distance of 1.9± 0.5 kpc away from the Sun, and has an age greater than 50 Myrs.
