Hi all,

I have just added this object to my observing schedule. Hopefully tonight I will already have clear skies.

Hi all,

In the 2009 superoutburst, this object showed five rebrightenings.
The rebrightening type and the superhump period of 0.061327 d imply that this object is a good candidate for a period bouncer, but the early superhump and growing superhump have not been observed yet. Time-series observations are strongly encouraged to confirm the system parameters.

Best,
Keisuke Isogai
