We
could get more of this kind of activity in the next 7 to 10
days. It will take about that long for the sunspots to cross
the face of the sun. The sun's rotation is turning the spots
toward Earth, which means the next CME, if there is one, might
not miss. CME strikes do no physical harm to Earth but they
can cause Northern Lights, satellite glitches and, in extreme
cases, power outages.
