Abstract
ABSTRACT The very short-period W Ursae Majoris system VZ Psc was observed on two consecutive nights with the facilities at Lowell Observatory. The observations covering the eclipse portions of the light curves yielded four epochs of minimum light and an improved ephemeris. A period study covering nearly 27,000 cycles revealed that the period has remained rather constant with no discernible long-term variation. The light curves, defined by 321 observations with the B filter and 317 with the V filter, display shallow eclipse depths and are highly asymmetric with maxima occurring at phases 0.29 and 0.72. The maximum following primary eclipse is somewhat fainter and redder than the maximum following secondary eclipse.
