Description
Broadband photoelectric light curves for the RS CVn type star PZ Telescopium are presented. The photometric period is about 0.943 days. The V light curve shows radical changes in form and range over a few months and may be continuously variable. In 1982 no (B-V) change with phase was detected. However, in the first part of the 1983 observing season a change of around 0.02 magnitude was found. Also at this time, maximum light was some 0.05 magnitude above that measured previously. Preliminary spectroscopic data indicate that P2 Tel is a double lined binary whose components are of approximately equal luminosities. It is suggested that the photometric variations are due to the presence of large cooler starspots on the photosphere of one or both components
