[vsnet-campaign-dn 1360] WZ Sge analysis of Aug 24/25 run : fading, double-peaked superhumps, well-pronounced eclipses
Dear colleagues,
I have now made my Aug 24/25 observations of WZ Sge available on-line at my
web site. The data were obtained under very clear and stable skies. The run
started at about 19:50 UT and continued for 7.1 hours, without
interruptions. I was using 20 sec (unfiltered) exposure times. The resulting
light curve is quite impressive and reveals a quick fading of the variable
(0.27 mag in approx. 7 hours, or about 0.9 m/d), clear double-peaked
superhumps, and multiple well-pronounced dips, mostly in the declining
branch of the superhumps. The eclipses are the deep dips, immediately
following the second superhump peak. Interesting to see how the overall
profile of the light curve has been changing compared to previous nights.
