Scientific paper

The two B and V light curves of the close eclipsing binary BV Draconis were obtained with a two-beam, multi-mode, nebular-stellar photometer, using the star SAO 166029 for comparison. It is found that both B and V maxima are equal in the two curves, and that the depth of the minima is nearly the same. Since there are many observational points for the phases from 0.0 to 0.55, both minima as well as the maximum following primary minimum are well observed. The dispersions obtained are small in the B curve and large in the V curve.
