[vsnet-superoutburst 835] WZ Sge results of Aug 29/30 : spectacular (5th) rebrightening !
Dear colleagues,
I just finished processing my WZ Sge CCD images of August 29/30, and was
overwhelmed by the resulting light curve ! I collected 714 CCD images over a
period of nearly 7.8 hours, between August 29.81 UT and August 30.13 UT.
During the initial 4.0 hours of the run, WZ Sge was humping more or less at
a constant brightness level, showing again complex modulations. But, it then
gradually started to brighten at a slow rate first, suddenly followed by an
extra-ordinary increase of 0.8 mag in 2.4 hours (or 0.33 mag per hour !).
This confirms the finding of Donn Starkey [vsnet-alert 6510] and shows that
the rise to maximum brightness was at an even higher speed than initially
pointed out by Donn.
As expected yesterday, it's now cloudy over Belgium - and it's likely gonna
stay like this for a number of nights.
I have made my August 29/30 light curve available on my web site, as always.
Have fun and please continue the dense monitoring WZ Sge !
