ER UMa: short-period negative superhumps confirmed

   We have received new observations from Denis Samsonov (Crimean Astrophys.
Obs., relayed by E. Pavlenko) following the present outburst maximum.
The object was fading (relatively slowly) with increasing signal of
negative superhumps.  The data, combined with earlier data, have confirmed
a period of 0.06193(6) d (2.7% shorter than the Porb, correction).
