[vsnet-outburst 8765] CR Boo: superoutburst

CR Boo: superoutburst

We observed CR Boo, whose bright outburst was reported last 
night (by G. Poyner in cvnet-outburst).
We detected superhumps with a period of ~0.017 d, which indicate 
that the current outburst is a superoutburst.
The superhumps were also detected in the J-band. 　
They have a similar amplitude, and possible secondary humps 
in the J-band.

It is noteworthy that the V-J color is quite blue (V-J~-0.5). 
This is comparable to the color of WZ Sge stars at supermaximum.
