[vsnet-alert 9315] GW Lib is in a normal superhump phase

[Arai Akira]

We found superhump-like variations with amplitudes of about 0.1 mag in the light curve of GW Lib tonight.

Our preliminary analysis provided a period of 0.0540+/-0.0009 day.
If this period is real, 
the humps is probably superhumps, whose superhump excess is about 1.1%.

GW Lib is now in a normal superhump phase.
