ER UMa: period of negative superhumps

   Using observations since the first normal(?) outburst, we have obtained
a period of 0.062450(5) d, which is substantially shorter than the period
during the superoutburst.  The period looks almost constant during these
stages (both outbursts and quiescence).

   More analysis will be presented by Ohshima-san.
