ER UMa: multiple maxima appeared again?

 We have received further obsevations  from de Miguel, Krajci, 
and Akazawa-san. Obtained data shows that this object still 
shows negative superhumps. Interestingly, secondary peak got
stronger in Krajci's data (Feb. 11). Such profile appeared around
Jan. 25 ~ 26. While the previous case is in the superoutburst,
the present case is in the minimum. The amplitude of superhumps
were still large, reaching 1 mag. This is unusual.

 Further observations are still encouraged!
