OT_J102146.4+234926 still bright: AL Com like?

    The object had rebrightened last night (vsnet-alert 9150), 
and it is still bright tonight:

20061121.83438   14.420 +/- 0.005 C   superhumps detected
20061127.81359   16.036 +/- 0.007 C   faded
20061128.83461   14.840 +/- 0.006 C   rebrightening !  ***
20061129.81038   14.884 +/- 0.031 C   rebrightening continues.

    It remains at almost same level compared with the last night
observation.  It implies that the rebrightening of this object 
may be similar to that observed in AL Com (Kato et al., 1996; 
Nogami et al.1997), that is, a long superoutburst is 
terminated by a temporary dip, and then the second plateau appears. 
Superhumps disappeared during the second bright phase of AL Com in 1995.  
We need to take time-series runs in order to see what happens in 
the current case of OT_J102146.4+234926.

*** I reported a wrong observation time yesterday:
> 20061128.33461   14.840 +/- 0.006 C
should be
  20061128.83461   14.840 +/- 0.006 C
Sorry for confusion.
