SS Aur: QPOs

     A. Simon (Lisnyky observatory, Ukraine) and Kyoto U. team have
reported the further observations. Th light curve had show violent
oscillations with the amplitude of 0.2-0.4 mag. Because there is no
constant period, the oscillations are not spins but QPOs.
     Time-series observations are not so important in the present state.
