ER UMa: positive superhumps confirmed

   Elena Pavlenko (Crimean Astrophys. Obs.) has reported further observations.
All the available data up to now have confirmed that positive superhumps
rapidly evolved (amplitudes 0.03 to 0.27 mag in 6 cycles).  The period has
been relatively constant at 0.06608(2) d (3.8% longer than Porb).
It would be very interesting to see whether negative superhumps develop
from these positive superhumps!
Further analysis will be presented by Ohshima-san.
