  • 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.
