ER UMa: superhumps had evolved!

 We have received further observations from Enrique 
de Miguel and William Stein. According to these data,
this object started a superoutburst and positive 
superhumps have evolved whereas negative superhumps
had disappeared. Interestingly, the phase of positive
superhumps and negative superhumps seems continuous,
such as the case of last year.

 Further observations are strongly encouraged!
