HT Cas: on Nov. 5-6

   We have received very intensive observations from Maehara-san, Okayama
U. of Sci. team, Akazawa-san, and past observations from Gianluca Masi.

   On Nov. 5-6, the superhump maximum passed the center of eclipse and
a very remarkable beat phenomenon was observed.  During this passage,
the eclipse became very shallow (only 0.2-0.3 mag below the mean brightness)
and the amplitudes of superhumps were very reduced.  Following this
phenomenon, the amplitudes of superhumps and depths of eclipses
started to grow again.
The mean superhump period since Nov. 4.2 has been 0.07659(9) d
(3.9% longer than Porb).
