V677 And: double-wave modulations

   Lew Cook has reported time-series observations.
The object indeed shows double-wave modulations
but the period is 0.07308(2) d.  The profile does
not resemble those of superhumps and this object
may be a polar in high state (two-pole accretor).
According to ATEL 1750, He II feature was observed
during the 2008 "outburst".
This feature (depending on the strength) is compatible
with the polar classification.
