OT_J102146.4+234926: modulations after the superoutburst

    The object remains faint.  We have updated our web page:

http://home.hiroshima-u.ac.jp/~uemuram/J1021/J1021.html

The fading trend seems to be stopped at 18 and 19 Dec. (V~18.7). 

   The above page now includes light curves of short-term variations 
observed in 15, 18, and 19 Dec., just after the superoutburst.  
While the light curve on 15 Dec. is filled by rapid fluctuations, 
the light curves on 18 and 19 Dec. show a simple hump. 
Our preliminary period analysis of 18 and 19 Dec. data yielded 
0.0561 d.  This is shorter than the superhump period (0.05628 d) 
and possibly be an orbital period, although we need more data
to determine their accurate period.
