Have observed it last night. V mag = 10.948 +/- 0.006
I Mag 11.00 +/- 0.014

Will start timer series tonight. Should I use V or Clear filter?

Groeten,

PNV J19150199+0719471: early superhumps?

   Enrique de Miguel's report.  A run on another night may
clarify the nature of the variation.

Comments:      0.35 mag fainter than 24 h ago.
               There are obvious oscillations in the light curve.
               The main frequency (36.1 c/d) could be just the
               1st harmonic of double-humped early superhumps.
               This would be involve a periodicity of 0.0554 d.
               More likely a WZ Sge-type object than a Nova,
               but still to be checked.
