ER UMa : ordinary superhumps developed

 We have further observations from Okayama Univ. of Science team (including
Akazawa-san, Kasai-san, Josch Hambsch, Tom Krajci, and William Stein.
Ordinary superhumps appeared clearly and their amplitude reached ~ 0.3 mag.
The variation of superhump period is not clearly seen at present. It is 
interesting that there appeared to be no phase shift between negative
superhumps and positive superhumps.
 Further observations are required!
