         MINIMA OF ECLIPSING VARIABLES


      The eclipsing variables were observed visually by
the writer in Fort Skala Observatory near Cracow with the
Expedition Refractor O = 203 mm, f = 227 cm, expect Beta
Per. The heliocentric moments of minima were determined by
tracing - paper method, "n" behind moments of minima denotes
normal minima and column "N" denotes number of observations.
Column O-C was computed with elements given in "Rocznik
Astronomiczny Observatorium Krakowskiego 1971".
