CSS J174033.5+414756: almost zero Pdot

   Maeda-san, Osaka Kyoiku U. team (Kazunari Masumoto, Hirochika Nishino, 
Miho Kawabata, Daisuke Sakai, relayed by Katsura Matsumoto),
Crimean Astrophys. Obs. team (Roman Zvagelsky and Elena Pavlenko),
Ian Miller and Enrique de Miguel have reported new observations.
The period has been almost constant at 0.045487(5) d with
Pdot = 0.0(5)*10^(-5).  The decrease of the superhump amplitude
stopped and there may be even a sign of regrowth.  Further observations
are still needed.
