ER UMa: negative superhumps with a short period

   During the present outburst, an analysis has yielded a markedly
short period 0.06180(9) d, more than 5% shorter than the orbital period.
This change in the period may have been a result of change in the disk
(i.e. different periodicity starts to grow, or precursor event for
the next superoutburst).  Please continue the current coverage to
continuously follow the development.
