CCD photometry of the open clusters NGC 2671 and anonymous Haffner 17 (C0749-317)

A preliminary UBV photometric study, based upon new CCD observations, is presented for the central region of the open clusters NGC 2671 and Anonymous Haffner 17 (C0749-317). Using a zero-age main sequence fitting computer package, the average reddenings and distance moduli for the two clusters were determined yielding EB-V(B0V) = 1.04 +/- 0.02 (s.d.) and V-0 - M-V = 11.1 +/- 0.5 (s.d) for NGC 2671 and EB-V(B0V) = 1.26 +/- 0.04 (s.d.), and V-0 - M-V = 12.3 +/- 0.2 (s.d.) for C0749-317. An estimate of the clusters age was also made resulting in values of 8 x 10(7) yrs and 5 x 10(7) yrs, for NGC 2671 and C0749-317, respectively. The latter cluster seems to locate near the continuation of our local spiral arm feature.
