GW Lib: rapid fading stage

Our tonight observation (7 May) shows a rapid fading of GW Lib. 

http://kanatatmp.blogspot.com/2007/05/gw-lib-rapid-fading-stage.html

The fading trend continues at least for the last 4.5 hours, 
and its speed is about 1.2 mag/day. 
It indicates that the rapid fading phase has started just now. 
With the monotonous fading, we can see several short-term 
modulations in the light curve.

After this temporary fading, GW Lib will probably experience 
rebrightenings, which are frequently observed in WZ Sge stars. 
The object is now in a rapidly evolving phase again.

Follow-up observations are urged.
