ER UMa: positive superhumps continues

  We have received further observations from Boyd Boitnott, Pavol
A. Dubovsky, and Josch Hambsch, and Shiokawa-san and Itoh-san.
According to these data, clear superhumps with 0.2 ~ 0.3 mag were
seen. The proifile is typical of ordinary SU UMa type dwarf novae.
The amplitude of superhumps varies in scale of ~ day. This may be
due to a beat of the disk although only two days have passed since
the start of plateau stage and the length of observations is not 
enough to confirm this.
  It is bery interesting how this object behaves. Further observations
are required!
