[vsnet-alert 6440] WZ Sge: partial results from last night observations

[Gianluca Masi <gianmasi@fr.flashnet.it>]

Dear Colleagues,
after some days of silence, finally I've been able to track again this amazing
star. I observed for 5 hours, starting at 21:00 UT. Images were grabbed every 14
seconds, each exposure being of 9 seconds. I reduced about 50% of the run and
here are some preliminary results (I have also one hour of data between 18:50 UT
and 20:00 UT).

The curve is very interesting. While there are no large humps (>0.2mag), some
short-term modulation seems to be clearly present (period of 0.015d), mainly
during the first hour; the final part shows a little "dip" . Eclipses have a
weak importance, at least in this part of the run. I confirm a fading trend for
the star.

The light curve, with others curves from previously unpublished datased will be
added later today.

Kind Regards,
Gianluca
