[vsnet-campaign 517] IY UMa last observation at Kyoto




  I am now seeing the light curve of IY UMa observed last night at Kyoto.
The altitude of the object was very low and the data is noisy, 
but I can see an eclipse-like feature around September 29 9:36 (UT).  
This is about 16 min faster than the prediccted timing.
During our run, out of eclipse (29.41 - 29.46 UT), the object brightened 
with a rate of 1.2mag/d, and then, showed a possible fading.  
This may be a superhump or the next eclipse.  
I have checked the constancy of comparison.

  Can anyone have a plan to confirm the current status of IY UMa?
At Kyoto, it will be rainy tonight.  The nature of this outburst is 
still not unclear.

Regards,
Makoto Uemura
