OT J145921.8+354806: period variation

   Gianluca Masi has reported new observations.  The mean superhump period
based on 4-night observations is 0.08499(5) d.  There is a clear decrease
in the period with Pdot = -18(5)*10^(-5).  Although many long-Psh
SU UMa-type stars tend to show large negative Pdot's, systems with
rare outbursts (like this object) are known to show more usual Pdot's.
It would be interesting to follow the evolution of the superhump period
in this system.
