[vsnet-alert 9358] GW Lib: no rebrightening, period changes of late superhumps

[Taichi Kato]

   We have received more data from Berto Monard, Nakajima-san,
and Kiyota-san.  The coverage since the rapid fading has been
extremely good.

   There is yet no indication of a rebrightening.  The mean
brightness of the object has smoothly declined.

   The superhumps (late superhumps) are still very pronounced,
with nearly sinusoidal profiles on most recent nights.
The period of late superhumps now shows a slow decrease.
More analysis will be undertaken by Imada-san and others.
