• Solar Cycle 23, how can we miss you if
  you won't go away?

  
  

  Barely
  three months after forecasters announced the beginning of
  new Solar Cycle 24, old Solar Cycle 23 has returned.

• What's
  going on? Hathaway explains: "We have two solar cycles
  in progress at the same time. Solar Cycle 24 has begun (the
  first new-cycle spot appeared in January 2008), but Solar
  Cycle 23 has not ended."
• 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.
