SDSS J090221.35+381941.9: shorter superhump period

   Enrique de Miguel, William Stein and Pavol A. Dubovsky
have reported new observations.  The period since Mar. 19 
has been 0.03376(2) d, only 0.6% longer than the orbital period.
This shortening of the superhump period may suggest
stage A-B transition, but requires confirmation.
The behavior varies almost nightly and continuous
observations are urged.
