       PHOTOELECTRIC MINIMA OF ECLIPSING VARIABLES

       In the table thirteen minima of eclipsing binaries
are given, obtained photoelectrically at the Bucharest 
Astronomical Observatory, (O-C)-s were computed with the elements
given in "Rocznic Astronomiczny, 1968" for the first nine
minima and from the "Finding List for Observers of Eclipsing
Variables, 1963", for the last four stars, respectively.
