WZ Sge: short-term variations in optical spectra

    Accorging to the report from Dr. Sadakane, observing at Okayama 
Astrophysical Observatory, both emission and absorption components 
of H-beta show strong short-term variation (reported on July 24).

    Since the object is very bright, even small telescope will be 
able to obtain time-resolved low resolution spectra.  Such time-series 
spectroscopy will provide enormous hints for the dwarf nova outburst and 
the early superhump.  Observations are strongly encouraged.  If possible, 
observations covering more than one orbital period are prefered.
