   This object underwent a superoutburst in 2004 November.  Only a single
normal outburst has been recorded since.

Some historical references:
vsnet-chat 3317 (ROSAT selected)
2004 March 2: Schmeer, first outburst detection
2004 November 1: Schmeer, superoutburst

   The overall behavior and the superhump period suggest resemblance
to UV Per and VY Aqr.
