HT Cas: growing superhumps!

   See Enrique de Miguel's report attached.  Almost nothing more to add!

   The superhump period determined from de Miguel's run is 0.0766(3) d
(4% longer than Porb), but earlier epochs (since Nov. 3.45) have been
well expressed by a period of 0.0793(4) d (8% longer than Porb).
The eclipses have became systematically shallower and broader as
superhumps grew (already evident in runs in Japanese).

   Many observers have used high temporal resolutions (~10s including
the readout time), and given excellent results.  If possible, please
use short integration times to record the details of eclipses.

Probably, the nicest light curve I've ever got,
where one can witness the onset of large-amplitude
superhumps, initially almost in phase with the orbital
eclipses, but later out of phase (Psh > Porb)
