ER UMa : negative superhumps

 We have received further observations from Akazawa-san and Pavol A. 
Dubovsky. This object seems to last brightening. However I am sorry
for reporting wrong information in  the previous mail. Positive
superhumps have not appeared in this superoutburst, instead negative
superhumps were seen.

 Further observation are strongly required!
