ER UMa: gradually declining

  Akazawa-san, Okayama U. of Sci. team, Shiokawa-san, Tom Krajci,
and Kyoto team have reported observations of this object. Obtained
data shows that this object is decllining to the minimum, however,
~ 0.5 mag superhumps still have been seen while the period is 
also still that of negative superhumps. 
  It is interesting how this object will behave in the minimum
and how long the negative superhumps remain. Futher observations
are still required if you can.
