      After reaching the 700 km/sec mark, the solar wind speed is beginning
      to slow down as the Earth exits a coronal hole solar wind stream.
      Although the solar wind speed was high, the interplanetary magnetic
      field stayed oriented to the north most of the time, which suppressed
      geomagnetic activity. There is but a single tiny sunspot region
      visible, and it doesn't look to have the ability to produce
      significant flares at the present time. There is another coronal hole
      swinging into view, and we could see some high speed solar wind gusts
      from it around the first of next week.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 11
      SFI : 75
      A index : 12
      K index : 1

      Solar wind speed : 590.2 km/sec
      Solar wind density : 0.8 protons/cc
      Solar wind pressure : n/a

      IMF : 3.9 nT
      IMF Orientation : 2.7 nT North

      GOES-12 Background X-ray Flux level : A2

      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 continue at very low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to continue at quiet to unsettled
      levels. Quiet levels are expected on 04 and 05 March as the high speed
      solar wind stream rotates out of a geoeffective position.

      Recent significant solar flare activity :
      None
