      spotted in Alaska. An aurora watch remains in effect. Skywatchers in
      northern Europa, Canada, and Alaska should keep an eye out for aurora,
      especially around local midnight. The current conditions are expected
      to last for about the next 48 hours before the solar wind speed starts
      to slow down. Of the suspot regions visible, region 547 looks to have
      a chance of generating a significant flare.
