OT J214332.9+461222: rapid decrease of the superhump period

   Crimean Astrophys. Obs. team reported further observations.
The object has showed a strongly negative Pdot = -70(11)*10^(-5).
This probably reflects a delayed stage A-B transition
in a very long Porb system like past examples of MN Dra.
