EI Psc on Oct. 10

   Akazawa-san (Okayama U. of Sci. team) has reported time-series observations
of EI Psc on Oct. 10.  There were well-defined waves.  An analysis has yielded
a period of 0.0441(1) d, confirming that this period arises from orbital
variations rather than superhumps.  The full amplitudes of variations
were 0.2 mag, but the profile is more singly-peaked rather than the typical
one (ellipsoidal modulations) in quiescence.  There may have been significant
contribution from the disk (even superhumps?).
