ER UMa: negative superhumps

 We have received further observations from Akazawa-san,
Kasai-san, and Josch Hambsch.
 According to these data, this object was at minimum.
Though negative superhumps were clearly seen, the profile
was not stable. Both steep peaks and gragual peaks were
seen unlike ordigary superhumps. 

 Further observations are encouraged!
