OT_J021110.2+171624: fading from the superoutburst

We found that the object faded from the superoutburst on 13 Feb. 

YYYYMMDD(UT)     mag.   err.
20080209.49753  15.58V 0.14  Higashi-Hiroshima Observatory
20080213.43904  18.70V 0.17  Higashi-Hiroshima Observatory

It was still in superoutburst on 9 Feb. 
The duration of the superoutburst is >11 days.

The object is a new SU UMa-type dwarf nova, originally 
discovered on 30 Jan by Catalina Sky Survey.
Its quiescent counterpart is a R=19.2 mag star. 
Our observation on 13 Feb. shows that the object has almost 
reached the quiescent level. 
The lack of a long fading tail after superoutburst indicates 
that this object is not a WZ Sge-type star, but an ordinary 
SU UMa-type one.
