ER UMa: persisting negative superhumps

   Shiokawa-san and Enrique de Miguel have reported further observations.

   Negative superhumps have been persistently present during the present
outburst.  The period has been essentially stable throughout the outburst
(0.06267(2) d), but the amplitude has been grown to 0.4 mag as the
object faded to ~14.4 mag.

   More analysis with newly coming data and encouragement for further
observations will be presented by Ohshima-san.
