GW Lib: rapid fading stopped

The rapid fading has been terminated, and GW Lib is now staying at 
a state ~4 mag. brighter than its quiescence. 
The V-J color is now about 1.0.

No significant fading trend is observed in these three days 
(9, 10, and 11 May), which may imply rebrightenings next week.

The superhumps are apparently growing in amplitude. 
The amplitude of the optical superhumps was 0.25-0.30 mag on 11 May. 
The infrared (J-band) superhumps had smaller amplitudes of 0.15-0.20 mag.
This indicates that the superhump source still has a relatively 
high temperature.
