      ** Aurora Watch In Effect **

      The Earth is still inside of a high speed solar wind stream tonight,
      and an aurora watch remains in effect. The activity has been fairly
      subdued, however, and the only aurora sightings occurred on the night
      of the 2/27 in northern Canada and Alaska. Nevertheless, G-1
      geomagnetic storm conditions were observed within the last 24 hours,
      so skywatchers in the higher latitudes should still keep an eye out
      for aurora. Look for isolated active periods tomorrow, with a gradual
      decline after than as the solar wind speed drops off. Of the two
      numbered sunspot regions visible, sunspot region 567 looks to have at
      least a small chance of generating as significant flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 42
      SFI : 90
      A index : 11
      K index : 1

      Solar wind speed : 571.1 km/sec
      Solar wind density : 1.4 protons/cc
      Solar wind pressure : 0.7 nPa

      IMF : 3.9 nT
      IMF Orientation : 2.8 nT North

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Geomagnetic storms
      reaching the G1 level occurred.

      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 low for the next three days (04-06
      March). Region 567 is expected to produce additional C-class level
      activity. There is a slight chance for an isolated M-class event.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be unsettled with some isolated
      active periods for 04 March. Mostly unsettled levels are expected for
      05 March and quiet to unsettled levels are expected for 06 March. The
      decrease in activity is expected from the slow decline of the high
      speed solar wind stream.

      Recent significant solar flare activity :
      None
