      THE NEW PHOTOMETRIC ELEMENTS OF BS DRACONIS


    During 1972-1974, 813 photoelectric observations of BS Dra
were carried out at the Astronomical Observatory of the University
of Cluj-Napoca.
    The observations were made in V and B light with a 50 cm
Newton reflector, a photometer employing an unrefrigerated 1 P 21
photomultiplier tube and Corning 3384 and BG 12 + GG 13 filters,
respectively.
     Table 1 contains the observed times of minima. Using the
minima published by Oburka (1971, 1972), Kizilirmak and Pohl (1974)
as well as those from Table 1, the following elements have been
determined: Min I = J.D.hel.2426444.5834 + 3.363988d E

     The real period is twice as long as the value published in
G.C.V.S. (1969).
     The O-C differences calculated with the new elements are
also given in Table 1.
     The general picture of the mean light curve in V is plotted
in Figure 1, whence we can see that the secondary minimum occurs
at the phase 0.5p. The computation of the orbital elements is in
course of preparation, and they will be published elsewhere.
