HT Cas post-superoutburst superhumps

   We have received further data from Osaka Kyoiku U. team, Akazawa-san,
Maehara-san, Kyoto team (Ohshima-san), Ian Miller, Seikei High School team
and Nick James.  Ian Miller's observation on Nov. 14-15 caught the late part
of the rapid fading phase.

   Superhumps (likely stage C superhumps) persist in this phase.
The best period outside the eclipses is 0.075907(1) d.
The mean profile of the late stage superhumps is generally singly peaked
with amplitudes 0.28 mag (earlier phase) and 0.20 mag (later phase, with
some more structures).  The eclipses were generally 2 mag deep with
more flatter bottoms (the eclipse of the white dwarf seems to be emerging).
