Scientific paper

A UVBY analysis of HR 8102 is presented. From recent data, a mean period of variation is found to be 0.097 d. A mean effective temperature of 7640 K and an average effective gravity computed over the pulsation cycle of 3.91 are derived over a pulsational cycle. The absolute visual magnitude is found to be 1.45m. These values suggest that HR 8102 is a normal Population I pulsating star and a member of the Delta Scuti group.
