Re: Late superhumps in WZ Sge

Dear Colleagues,

   Just a comment.  If WZ Sge may fade, and become difficult to measure
with conventional photometry softwares, please send us raw images.
We are fully prepared to make necessary PSF photometry even under difficult
conditions.  Just to ensure bright stars (PSF standard candidates) are
not saturated.  At 15-th mag, there is no problem to measure 10-s exposures
(or even 5-s exposures) with 20-30 cm telescopes.  Please continue
observing as long as you can!  For WZ Sge, a duration of 100 d since the
start of the outburst would be a roughly acceptable estimate of the required
intensive campaign.  (Please note the cooling time of the white dwarf
was a few times longer than this on the occasion of the 1978 outburst;
white dwarf specialists should stay longer :-)
