Dear colleagues,
About 2.5 hours ago (Nov 14/15, 2001), I started an unfiltered CCD run on DM
Dra, using the 0.35-m f/6.3 telescope at CBA Belgium Observatory and ST-7
CCD. The intermediate light curve already clearly shows the presence of
superhumps (amplitude about 0.35 - 0.4 mag). It's too early to make an
estimate of the superhump period, but I will continue to observe the object
as long as possible. Weather over Belgium is very stable now (extremely
clear skies).
I will report further analysis results in a few hours (before heading off to
Flagstaff, Arizona to observe the Leonids).
Best regards
Tonny Vanmunster
