   According to basvss alert, the dwarf nova V651 Oph is in outburst.

Subject: [baavss-alert] V651 Oph

I detected the V651 Oph in outburst last night at mag ~ 16.5 which is 
my first positive identification, To the best of my knowledge, it is 
classified as a CV of unknown type. The last reported outburst was Apr 
13, 2006 by Patrick Schmeer at mag 16.7 CR.

It will be raining here for the next few nights so I will not be able 
to follow-up, I thought I would pass this along if any one is 
interested in observing this star.
Clear skies to all!

AN 271.1936 = V651 Oph

- "Die Existenz des Sterns ist durch gute Platten gesichert,
ebenso die Unsichtbarkeit. Anscheinend ist der Stern nur selten
und fu"r kurze Zeit hell. Mira-Art scheint nicht vorzuliegen."

  Bright on one scan, otherwise at or near minimum.
A great chance that this is a short period CV.

   The object has a ROSAT counterpart:

183841.4 +092233 (2000.0) 1RXS-F_J183841.5+092234 0.021 1.00 0.58
