UV Gem: new data and superhumps update

Dear Colleagues,

   We have received new sets of data from Tonny Vanmunster, Nyrola Observatory
team (Petri Tikkanen and Arto Oksanen), Ouda (Ishioka-san).  The data
from Kyoto, Okayama, Torii-san (RIKEN) are also steadily growing.

   The most recent data still confirm the shortening of the superhump
period.  The mean Pdot up to now (disregarding the initial phase of a sudden
period change) is about -2.8*10^-4.  This is the largest ever measured rate
of superhump period changes with a sufficiently long baseline.  We are
further analyzing the entire huge volume of data to fully illustrate
the peculiarity of UV Gem.

Regards,
