Abstract:
Photographic UBV photometry of 1302 stars in a 76 square-arcminute field
in the Puppis window to U∼16.9, (B, V)∼21 is presented. The presence of
an OB association at r∼6kpc in this direction as reported by Stetson
and FitzGerald (1985) is confirmed. No evidence of any more distant
early-type stars is indicated.
