Abstract

New UBV observations of a contact binary AB And obtained during 1988, 1989, 1990, 1991 and 1992 observing seasons at the Ankara University Observatory are presented. Sixteen new (nine primary and seven secondary) times of minimum light were obtained. The new times of minima reveal the following improved light elements: MinI = HJD 2448513.54325 + 0.33189044 E.
