ER UMa : negative superhumps at minimum

 We have received further observations from 
William Stein. According to thes data, this
object was at minimum. 
 The interval of last two normal outbursts 
is shorter (5d) than them before the last 
superoutburst (7~10d). This shows the next 
normal outburst may occur soon as well as 
this may imply a change in the disk. Thus
the lack of observations is expected to be
avoided as possible.  Further observations 
are encouraged!
