                 DOUBLE-LINED ECLIPSING BINARY
                    BV 382 CEPHEI HD 205372


    This star was previously announced as an EW binary having
the period 0d.483; (1) (2) (3).

     Spectroscopic and photoelectric observations made respectively 
at the Astrophysical Observatories of Asiago and Bologna show
that the variable is a double-lined system whose period is approximately 
twice the old one. The spectral types of both components are
about A0 V, so that the binary belongs to the beta-Lyrae type.

   The following preliminary elements have been derived;
   P = 0d.936171
   T_0 = 2438225.6858 JD (primary minimum)
   e = 0.00, V_0 = -22 km/s, i = 71deg
   K_1 = 172 km/s, K_2 = 187 km/s
   a_1 = 2.3x10^6 km, a_2 = 2.5x10^6 km
   r_1 = 1.8x10^6 km, r_2 = 1.7x10^6 km
   m_1 = 2.7(solar), m_2= 2.5(solar)
   rho_1 = 0.16(solar), rho_2 = 0.16(solar)


      Further results will be given in a paper which is now in print.

              Remark to Bulletin No.80

      On the little chart the variable is hardly to be recognized as a
small ring. The variable is the star 9.4 mm from the right side and
3.8 mm from below.
