      ** G-2 Geomagnetic Storm In Progress **
      ** Aurora Watch In Effect **

      The last couple of nights have seen quite a bit of geomagnetic
      activity, and its not over yet! The Earth is still inside of a
      coronal hole generated solar wind stream, and the Interplanetary
      Magnetic Field has been south-pointing much of the time. At one point
      the geomegnetic storm conditions were up to the G-3(strong) level.
      Aurora have been seen and photographed as far south as Arizona. See
      this link for some great aurora pictures from numerous locations
      across Europe, Canada, and the US. The current level of activity is
      forecasted to last at least one more day, and more aurora are possible
      tonight. Meanwhile, sunspot region 134 continues to be a threat for
      flares, and sunspot region 137 looks like it could also be a
      flare-producer.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 99
      SFI : 136
      A index : 35
      K index : 6

      Solar wind speed : 476.4 km/sec
      Solar wind density : 6.1 protons/cc
      Solar wind pressure : 2.0 nPa

      IMF : 13.6 nT
      IMF Orientation : 8.6 nT North

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been strong. Geomagnetic
      storms reaching the G3 level occurred. Radio blackouts reaching the R1
      level occurred.

      Forecast for the next 24 hours :
      Space weather for the next 24 hours is expected to be minor.
      Geomagnetic storms reaching the G1 level are expected. Radio blackouts
      reaching the R1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be low to moderate. A chance for an
      isolated M-class event exists from Region 134 (N13W29) and Region 137.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to active levels
      through the first day of the forecast period. Quiet to unsettled
      conditions are expected for the remainder of the forecast.

      Recent significant solar flare activity :
