[vsnet-campaign-dn 1109] WZ Sge multicolor photometry

[Lew Cook <lcoo@yahoo.com>]

Arne Henden, Dirk Terrell, Chuck Pullen and I collaborated on WZ Sge,
observing in 4 different colors. We have CCD observations from our 4
observing locations in U, H-alpha, V and B  (but not all
simultaneously), on July 28 and 29 UT when the star was flickering.

We have the U, B, V, and H-alpha curves plotted together and also the
color curves - U-B, B-V and B-Halpha. In summary, we find the
flickering is greatest in U and the other colors track the B closely
with only a few differences. 

Our preliminary light curves and some interpretations are presented
