VV Pup active

    As reported by R. Stubbings in [vsnet-outburst 6766], 
the polar (AM Her system), VV Pup is active. 
Short-term variations seem to be observed within one hour.  

    X-ray observations have recently indicated that mass-transfer 
rates are variable and irregular in VV Pup and other polars at their 
low states (Pandel, Dirk & Cordova, France A. 2005). 
In the current onset of an active state, X-ray and optical time-series
observations may be valuable in order to reveal the mechanism of 
the mass-transfer variation.
