            PHOTOMETRIC OBSERVATIONS ON SZ Psc

   Photometric observations of SZ Psc relative to the comparison star HD
219018 were obtained on 19th 20 August 1986 and 20th through 23rd September
1986. The data are shown in Fig. 1 as standardized deltaV plotted against 
photometric phase computed according to the ephemeris by Percy (1985).
    Primary minimum = HJD 2442308.843 + 3.965404d E - 1.13 x 10^-7 E^2,
    Although the entire minimum was not observed it is clear that minimum
light occured later than predicted by approximately 9.5 hours or 0.10 phase.
Some colour data were obtained in August and the exit from eclipse is plotted
in Fig. 2 as a function of UT on the night of August 20th 1986.

    The check star HD 219114 was observed 13 times and its magnitude relative
to HD 219018 was found constant at DeltaV = 0.185+/-0.007. The August data were
obtained with the 1 m SSO telescope using the Twin channel chopper, the September
data were obtained using the 0.4 m SSO telescope with a single channel
photometer. I thank the Australian National University for the use of these
telescopes.
