   Sorry for the late reply for that eclipse, but this information may be
of any help for the coming eclipses.

   The eclipse of IP Peg usually last 20-40 min (depending on the size of
the accretion disk).  So the time resolution less than 30 sec is recommended
(shorter the better, as long as the S/N allows).

   Typical light curve of IP Peg can be seen at (or followed from)

   Eclipses of dwarf novae is most interesting during the early outbursting
stage (the accretion disk is rapidly expaning).  Please put your keenest
focus on this stage on the next occasion!
