PNV J20205397+2508145: ordinary superhump

   Enrique de Miguel has reported recent observations.
Ordinary superhumps were already visible on Sep. 21-22
(let's hope it is still stage A).
The last observations were reported by Domenico Licchelli
on Sep. 19.  There has been a gap in the observation
on Sep. 20 and early Sep. 21, when ordinary superhumps
should have evolved.  If you have observations during
this period, please report them.
(This one-day gap in observations during transition
to stage A is commonly seen in many objects, suggesting
that there is a common underlying reason).
