      PHOTOELECTRIC MINIMA OF ECLIPSING VARIABLES


    The list below contains photoelectric minima of eclipsing
variables observed with the 60 cm reflector of the Konkoly Observatory. 
The observations were made with an EMI 9502B type unrefrigerated 
photomultiplier tube combined with 2mm UG1; 1mm BG12+2mm GG13
and 2mm GG11 filters. The colour is reported in the last column.
    Linear elements given in the 1969 General Catalogue of Variable 
Stars and its Supplements were used for computing the O-C values. 
N denotes the number of observations (each consisting of six
individual measurements).
