ER UMa: negative superhumps reappearing?

 We have received further observations from Enrique 
de Miguel. The reported data shows very interesting
variations. As the amplitude of superhumps got smaller
(from  0.25 mag to beneath 0.1 mag), the multiple
peaks got pronounced. It seems that negative superhumps
was appearing again.

 Further observations are encouraged!
