ER UMa: at minimum again

 We have further observations of Feb 20 from Stein.
According to this data,  ER UMa was at the minimum although
this object had been a little brighter on Feb 19, as
written in the previous mail. It seems that small brightening
occurred on Feb 19. Since the illegal pattern may appear, such
as the delay of the next outburst, continuously observations
are encouraged.
