COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 931 Konkoly Observatory Budapest 1974 October 7 PHOTOELECTRIC MINIMA OF ECLIPSING VARIABLES In the next table 11 photoelectric minima of eclipsing binaries are given. The observations were carried out using the 50 cm telescope of Bucharest Observatory. (O-C)-s are computed utilizing the elements given in Rocznic Astronomiczny 1974. Min. Hel.

We think that the moment of minimum for the star given in SAC 1974 is erroneous. PROF. CALIN POPOVICI Bucharest Observatory
