Abstract

This paper describes UBYRI-photometric observations of the double star BS6554 (p1 Dra) and B56555 ( Dra). Today, it is accepted that B56555 is a metallic-line star, Am; however, there `is not a general agreement as to whether BS6554 is an Am Star or not. The photometry indicates that probably both are variable stars. The variability amplitude is around 0.1 mag. At the first galance, the variables are irregular.
