      ** G-1 Geomagnetic Storm In Progress **
      ** Aurora Watch In Effect **

      Although the Earth is leaving a high speed solar wind stream and the
      solar wind speed is declining, G-1 geomagnetic storm conditions are
      being observed as I write this, and an aurora watch remains in effect
      for tonight. This event produced aurora what were seen and
      photographed at a number of locations across northern Europe, Canada,
      and the northern US. See this link for some impressive aurora
      pictures :

      Tonight's geomagnetic storm should be the last hurrah, and I expect to
      see conditions return to normal tomorrow. Sunspot region 570, once a
      large sunspot region, actually split in half over the weekend. It has
      lost some of its magnetic complexity, but still has at least an
      outside chance of producing a significant flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 61
      SFI : 103
      A index : 17
      K index : 5

      Solar wind speed : 428.2 km/sec
      Solar wind density : 1.5 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 5.7 nT
      IMF Orientation : 3.4 nT North

      Conditions for the last 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 very low to low. C-class activity is
      possible from Region 570.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled with
      isolated active periods.

      Recent significant solar flare activity :
      None
