ER UMa in minimum : negative superhumps continues

 We have received further observations from Enrique de Miguel and 
William Stein. According to these data, this object was at minimum
on Feb 28. Negative superhumps were still seen, and their period
is the value after the period change at the last outburst.
The next outburst will come soon within a few days. Something may
occurs abou the negative superhump period then. Further observations
are required!
