In the paper by Paula Szkody et al. "Cataclysmic Variables from SDSS.
VIII. The Final Year" the object has deserved a special note about the
spectrum (Figure 2):
> The visibility of a sharp peak component in the lines indicates a prominent hot spot may contribute to the light of this system.
The object has a very interesting light curve in CSS data:
Two bright outbursts were detected in 2005 and 2006 (14.1 and 14.3m,
respectively), then there was one night at 15.3 in 2008, after which
the object was never seen brighter than 16m. The quiescent magnitude
varies from below 18.5 to 17.6.
