[vsnet-alert 4650] IY UMa outburst confirmed



IY UMa outburst confirmed

   We started CCD time-series photometry at 10:30 (UT), 
and confirmed the outburst at about 14.3mag (preliminary photometry).
We are planning a more than 6 hours observation tonight.
More observations are strongly encouraged.
A short exposure time is recommended to cover the fine structure 
of eclipse profiles.

Regards,
Makoto Uemura and Taichi Kato
