FO And: refined superhump period

   Enrique de Miguel has reported further observations.  The mean superhump
period has been 0.07454(1) d.  As de Miguel has noted, there has been little
evidence of a systematic period change (yet).  The O-C curve suggests that
the period may be starting to decrease, possibly corresponding to a stage
B-C transition.  At this superhump period, the object may be on the borderline
of positive-negative Pdot for stage B superhumps.
