             MINIMA OF ECLIPSING VARIABLES



    The list below contains minima of eclipsing variables 
observed at the Fort Skala Observatory near Cracow. The heliocentric 
moments of minima and limits of errors were obtained by
the tracing-paper method. The letter "n" following moments of
minima. denotes normal minima and column "N" denotes the number
of observations. Column O-C was determined with elements given
in "Rocznik Astronomiczny Observatorium Krakowskiego 1973". The
observations were made with the Expedition Refractor o=203 mm,
f=227 cm, except beta Per.
