ER UMa: positive superhumps seen

 We have received further observations from Akazawa-san.
And we also took observations of this object.
 According to these data, this object was showing variations
like ordinary superhump. Although the observation duration
was not so long, the superhump period seems to be a positive
one. Since this superoutburst had continued for nearly one
week, negative superhump signal in this superoutburst may be
weak. If so, it's an important transient.

 Further observations are strongly encouraged!
