Long outburst (superoutburst of a WZ Sge-type dwarf nova?)
The only previously recorded outburst was observed
2008 August 6–28, with rebrightening(s) on August 31 and
September 3 (vsnet-alert 10485 and 10495).

 We report two newly discovered objects that are in need of confirmation
If somebody is able to make followup of this objects photometrically or
spectroscopically, we'd be interested to know. These objects were reported
also to CBAT.

Thanks in advance
