COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 1394 Konkoly Observatory Budapest 1978 March 17 PHOTOELECTRIC OBSERVATIONS OF V 711 TAURI According to the request expressed in IAU Circ. No 3089 the star V 711 Tau = HR 1099 was observed in Cracow Astronomical Observatory "Fort Skala". All observations were made by M.S. using 50 cm Cassegrain telescope (f=667 cm) with the photomultiplier EMI 9789 QB with filters: Schott GG11 and GG13+BG12, and calculations were made by P.F. The star 10 Tau=HD 22484 served as a comparison star, 12 Tau= HD 22796 and HD 22819 as check stars. Our observations corrected for differential extinction by using mean coefficients (A_B=0.55, A_V=0.4) are given in the Table.
