This is a dwarf nova that we observed only on a few occasions. We found it in quiescence in December 2000, February 2003, and January 2005. On one occasion, 13 January 2001, we caught it in an outburst, and the detection of superhumps suggested that this was a superoutburst. During quiescence it displays an orbital modulation with a period around 104min. Patrick Schmeer found it to be in outburst again on 11 April 2005, Jeremy Shears on 16 Feb 2006, both normal outbursts. Refining the superhump period would be good, if another superoutburst is detected.
