ER UMa: negative superhumps

 We have received further observations from Josch Hambsch.
 According to these data, ER UMa is showing negative superhumps.
In this superoutburst, positive superhumps were mainly seen during
the earliest 4 days. Otherwise positive superhumps appeared only
intermittently and shortly.
 Further observations are still continuously encouraged!
