WZ Sge: evolution of spectrum We have updated the VSNET WZ Sge web page. The page now includes an optical spectrum taken on July 25 by K. Ayani (Bisei Astronomical Observatory). He reported that the H_alpha absorption line became weaker than that on July 23, and emission line around 4670A (probably He II and C III/N III blend) has appeared! http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/wzsge01.html Regards, VSNET collaboration team
