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 ! Tonny Vanmunster CBA Belgium Observatory http://vsnet.lunarpages.com/cbabelgium email : Tonny.Vanmunster@advalvas.be
