QZ Vir superhump period: transition to a shorter period

   Bart Staels have reported further observations.  The data now clearly
show a transition from a positive Pdot phase to a stage of a shorter
period.  The transition occurred on Jan. 30.  Before this transition,
the mean period was 0.06039(2) d and Pdot/P = +8.7(1.5)*10^(-5).
After the transition, the mean period has been 0.06006(8) d.
The behavior generally well agrees with that of the past two recent
superoutbursts.
