ER UMa: negative superhumps intermittently seen

 We have received further observations from Enrique 
de Miguel and Josch Hambsch. These data shows the negative
superhumps appeared intermittently. This may be related
to the conjuction of positive superhumps and negative
superhumps.
 Further observations are encouraged!
