We find that the object is now in outburst (2 Nov).

The nature of the current outburst is unclear now. 
If it was a "rebrightening" observed after superoutbursts 
of WZ Sge/ SU UMa stars, it should have occurred earlier, usually. 
The object has, however, been brighter than quiescence 
for the last few weeks, which implies that the object has 
remained active since the last outburst.  So, the current 
outburst may have the same mechanism as the rebrightening 
phenomenon in WZ Sge stars.

Follow-up observations are urgently needed.
