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.
