      The solar wind speed has dropped back to normal levels since the most
      recent round of actvity. At least one person managed to capture a
      picture of aurora shining through the midnight sun twilight in Alaska,
      as can be seen here.

      Sunspot region 756, while still large enough to be naked-eye visible,
      is decaying in size and magnetic complexity. It never did manage to
      fire off a significant flare, although it did ccome darn close a
      couple of times, generating two C-9 events. It will soon be rotating
      out of view. The next noteworthy event will be another coronal hole
      solar wind stream encounter. A medium-sized coronal hole has rotated
      into an Earth-pointing position, and we should see the solar wind
      gusts from it in four or five days.

      The current solar and goemagnetic conditions are :

      NOAA sunspot number : 50
      SFI : 109
      A index : 6
      K index : 1

      Solar wind speed : 335.5 km/sec
      Solar wind density : 1.2 protons/cc
      Solar wind pressure : 0.3 nPa

      IMF : 4.4 nT
      IMF Orientation : 2.5 nT North

      GOES-12 Background X-ray Flux level : B2

      Conditions for the past 24 hours :
      No space weather storms were observed for the past 24 hours.

      Forecast for the next 24 hours
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be low with predominately B and C-class
      activity in Regions 756 and 758. There is a chance of a small M-class
      flare in either of these regions, as well.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled.

      Recent significant solar flare activity :
      None
