PNV J19150199+0719471: period of early superhumps

   By knowing the period of ordinary superhumps, we have been
able to choose the signal of early superhumps (this signal
was the second strongest after that of the ordinary superhumps).
The period was 0.05696(2) d and the mean waveform was doubly
humped.  The full amplitude (average) was 0.012 mag.
The current long superhump period suggests that we are (were)
indeed observing stage A superhumps.
