      All is calm for the time being, but things could get to be a little
      bit more interesting in the days ahead. First of all, the Earth
      should begin to move inside of a high-speed coronal hole solar wind
      stream within the next 48 hours. Also, a sunspot region that fired
      off a backside, full-halo CME on the 21st should soon be rotating into
      view. It will be interesting to see exactly what sort of magnetic
      complexity that sunspot region has when it emerges over the eastern
      limb of the solar disk.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 56
      SFI : 88
      A index : 6
      K index : 0

      Solar wind speed : 303.2 km/sec
      Solar wind density : 7.2 protons/cc
      Solar wind pressure : 1.2 nPa

      IMF : 6.9 nT
      IMF Orientation : 3.2 nT North

      GOES-12 Background X-ray Flux level : A7

      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. A region that
      produced a backside CME on LASCO imagery at 21/1448Z is expected to
      rotate on the East limb sometime over the next few days.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled with a
      slight chance for isolated active periods on 24 and 25 March. Activity
      is expected to increase slightly on 26 March as a recurrent coronal
      hole high speed stream moves into geoeffective position. Expect
      unsettled to active conditions on 26 March.

      Recent significant solar flare activity :
      None
