[vsnet-campaign-dn 197] IY UMa last night light curve

 
   In the light curve of IY UMa observed last night (October 10) at Kyoto, 
we can see an eclipse with the depth of ~2mag, and a possible 
small hump with the amplitude of about 0.1-0.2mag. 
The small hump may relate to main superhumps or late superhumps, 
so more observations are encouraged to confirm it.
Out of eclipse, the average magnitude is 15.02mag, which may imply 
the beginning of a rapid decline phase.

   Now we are observing IY UMa but it is sometimes cloudy.

Regards,
Makoto Uemura, Ryoko Ishioka, Taichi Kato, and Katsura Matsumoto
