Dear Colleagues,

We've just received further data (April 23) from Berto.
The data show five superhumps with an amplitude of 0.15 mag.
An estimated period of the superhumps is 0.0555(1) days. 
This value is about 0.001 days longer than that obtained 
by Kato-san. 

We photometrically confirmed that GW Lib is a ugwz star! 

Regards,
Akira Imada
