TCP J10203579+3103424: long-period early superhumps?

   Kyoto U. team, Itoh-san, Tamas Tordai and Kiyota-san
have reported observations.  An analysis has yielded
the possible presence of low-amplitude (0.025 mag)
early superhumps.  The profile looks double wave
with a period of 0.0806(2) d.  Since the signal is
weak, this period may be spurious.  But if correct,
the period is longer than ASASSN-16eg (0.07548 d).
The true period will become evident as ordinary
superhumps appear.  Please continue observations
to detect possible early superhumps and stage A
superhumps.
