Scientific paper

Results are presented of a radial velocity survey for 879 field stars in the direction (l, b) = (277, 9 deg) undertaken with the bench-mounted spectrograph, ARGUS, and echelle grating at the CTIO 4.0-m telescope. The radial velocity histogram shows a marked overabundance of stars in the range 74.0-76.0 km/s. Monte Carlo simulations indicate that this feature is significant at better than the 99-percent level. Fourteen of the 18 stars observed occupy a roughly horizontal locus in the field color-magnitude diagram. It is suggested that they are giants in an extended moving group at a common distance in the range 6-12 kpc. Features of the 18 candidate moving group members are presented in tabular form.
