ER UMa: transition from normal outburst to superoutburst?

 We have received further observations from Enrique 
de Miguel and William Stein. According to these data, 
this object reached the maximum of the normal outburst.
However, the decline from the normal outburst stopped
and turned into rising again several hours ago. Probably
the normal outburst was a precursor and this outburst 
will get to be a superoutburst.
 Such development of suoperoutburst was found in V344 Lyr
of Kepler data. However, ER UMa tends to start superoutbursts
without precursor outbursts (Especially, in superoutbursts
of last year).

 Further observations are strongly encouraged!
