SDSS J090221.35+381941.9: period variation

   Gianluca Masi and Roger Pickard have reported
new observations.  The recent observation appears
to give a longer superhump period (period increase).
Although this phenomenon needs to be tested by
further observations, it may be related to
a large disk radius (possibly beyond the 3:1
resonance) in such a superoutburst.
This object is still the top-priority target.
