[vsnet-alert 6398] Re: WZ Sge results of August 21/22 run at CBA Belgium

["Stan Walker" <astroman@voyager.co.nz>]

Hi Tonny et al,

Observations here in Kaitaia more or less confirmed what you said. I ran
from 22 August 0706 UT to about 1110 UT when cloud suddenly arrived. The
humps were ~0.05 at around phase 0.4. Two eclipses were visible, the third
was a little distorted. Overall, the star fell by about 0.12 in 4 hours. I
used a 10 second exposure time but should have stuck with the 20 seconds
I've been using lately. The S/N ratio might have been better. The weather
doesn't look promising at the moment but let's hope.

Regards,
Stan
