Brian gave another close-companion possibility, CW Mon. Most CVs are very blue, and it is easy to take a couple of CCD frames to confirm which star is the culprit. I can get reasonable colors at 20th magnitude in about 15mins of total exposure time with the 1.0-m, so even an amateur system should be able to at least check the 16mag possible companion to see its color. If no one has done so by my March observing run, I'll put the star on my program. Arne
