OT J015321.5+340856: negative Pdot

   Astrokolkhoz team (J. Hambsch and T. Krajci, the former data
referred to as J. Hambsch were also from Astrokolkhoz) reported
further observations.  The superhump period decreased and
we measured a Pdot of -174(19)*10^(-5).  This value is similar
to those of the in-the-gap systems MN Dra and NY Ser.
