ER UMa: new outburst had started!

 We have received further observations from Akazawa-
san, Enrique de Miguel and Josch Hambsch. The newest
data show that this obejct started the next outburst 
today (12 h before). Considering the waiting time
from the last superoutburst, this outburst may be a
superoutburst.
 Observations in the rising phase tend to be lacked
since the rising is often rapid. Further observations 
are encouraged!
