1965 light curves of BV Dra and BW Dra

Abstract

Differential B-band photometry of BV Dra and BW Dra, obtained in 1965, is presented. Times of primary and secondary minima are derived and combined with published times for a period study. Period variations are found in both binaries and magnetic cycles are proposed as an explanation. The cycle length is 19 years in BV Dra and 8 years in BW Dra.
