ER UMa : large QPOs

 We have received further observations from Sergey Shugarov, Crimean 
Astrophy. Obs. (obserevers: Oksana Antonyuk and Denis Samsonov), 
William Stein, and Tom Krajci. Additionally we (Kyoto team) also 
observed this object.
 According to these data, this object have been still declining. 
Interestingly, QPOs with large amplitude (~0.1 mag) were seen. 
Though variations like QPO had been seen before, amplitude was 
smaller and they were difficult to be determined as QPO.
 Further observations are required!
