      The level of geomagnetic activity has picked up a little since my last
      report, although it could hardly be lower, could it? The solar wind
      speed has actually dropped into the lower 300's, but the
      Interplanetary Magnetic Field has been dipping into a south-pointing
      orientation, which has increased the geomagnetic activity to the
      unsettled category. The solar wind speed is expected to increase in
      48 - 72 hours as the Earth moves into a high speed solar wind stream
      coming from something of donut-shaped coronal hole. None of the three
      small sunspot regions visible look to have the potential for
      generating a significant flare at this time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 93
      SFI : 98
      A index : 5
      K index : 3

      Solar wind speed : 321.1 km/sec
      Solar wind density : 3.6 protons/cc
      Solar wind pressure : 0.6 nPa

      IMF : 2.0 nT
      IMF Orientation : 1.0 nT South

      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.

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

      Recent significant solar flare activity :
      None
