[vsnet-campaign-dn 2215] CR Boo: atypical high-state

CR Boo: atypical high-state

    CR Boo is now possibly in an atypical high-state.  
The Kyoto team performed time-series photometry since the end 
of February.  Our recent CCD observatoins have revealed that 
the object has remained at Rc~13.6 and showed no significant 
fading since March 21.  While it may be a superoutburst, such 
state without fading is rather atypical for superoutbursts and 
is difficult to be explained with the disk-instability model for 
dwarf nova outbursts. 

    In the light curve, we can see short-term modulations.  Our 
preliminary analysis provided a weak periodicity of 0.01729 d, 
which indicates that they are superhumps.

Makoto Uemura
