ER UMa : positive superhumps still remaining?

 We have received further observations from Enrique 
de Miguel. Combined with these data, the negative
superhump period after positive superhumps weakening
is 0.06219 (5) d. However, when PDM analysis is applies
to the data separated daily,  positive superhump period
was obtained even after the positive superhumps weakened.
This may be because the shortness of data span, however,
this may show the blend of positive and negative superhumps.
Further observations are encouraged!
