Abstract
The present paper reports results of UBVphotometry of the triple-mode variable star, AC And. The metal abundance parameter AS is estimated from 8(U - B) and found to be 2.5 (+2.5). The (U - B) and (B - V) colors are compatible with the idea that AC And is an RR Lyrae star. Subject headings: stars: individual - stars: pulsation - stars: RR Lyrae
