ER UMa: negative superhumps in the last normal outburst

 We have received further observations from Akazawa-san, Sergey Shugarov,
Pavol A. Dubovsky, Bill Stein, and Tom Krajci.
 According to these data, ER UMa was at minimum on March 28. During the
normal outburst, the amplitude of superhumps changes vastly, however, the
period did not change although the dispersion is quite large. Using simple
lenear regression, 0.062390 (16) d is obtained.
 Further obsevations are required.
