Abstract

UBVI CCD photometry is obtained for the Ruprecht 93 (Ru 93) region. We are unable to confirm the existence of an intermediate-age open cluster in Ru 93 from the spatial distribution of blue stars. On the other hand, we find two young star groups in the observed field: the nearer one (Ru 93 group) comprises the field young stars in the Sgr-Car arm at d ps 2.1 kpc, while the farther one (WR 37 group) is the young stars around WR 37 at d « 4.8 kpc. We derive an abnormal extinction law [Ry = 3.5) in the Ruprecht 93 region.
