HT Cas: late-stage superhumps

   Polaris Observatory team (Hungary, Tamas Tordai and Robert Fidrich)
have reported observations including the rapid fading branch.
The data beautifully recorded superhumps in this stage.
The data up to now have confirmed that the period reported in
[vsnet-alert 12400] well express the phases of superhumps since the
end stage of the plateau phase and post-superoutburst phase,
i.e. there is no special indication for a phase jump expected for
"classical" late superhumps.  These results seem to strengthen
the interpretation that many "late superhumps" are indeed continuation
of stage C superhumps.
