              VELOCITY CURVE OF BV 312 TAURI



    45 spectra of the eclipsing binary BV 312 = BD +20deg 785 (1), with
dispersion of 42 A/mm at H-gamma, have been secured at Asiago
during the last two years. Radial velocities of this star were 
previously fully lacking (2). Only the spectrum of one component is 
observable in the blue region. The following uncorrected elements have
been obtained:

T0 =2438805.696 (3); P=2.056297day (3), (4); K = 68 km/s; y=-2 km/s; e = 0.

     Detailed results will appear later. So far no photoelectric 
observations are planned here.
