      ** Aurora Watch In Effect **

      The high speed solar wind persists this evening, hovering close to the
      500 km/sec mark, and an aurora watch remains in effect. Skywatchers
      in the higher latitudes should be on the lookout for aurora.
      Geomagnetic storm conditions at the G-1 level have been observed
      within the last 24 hours. The high speed solar wind is now expected
      to last for at least another 24 hours. Although solar activity has
      remained quiet over the last few days, sunspot region 296 has at least
      an outside change of producing an M-class flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 132
      SFI : 150
      A index : 18
      K index : 3

      Solar wind speed : 483.7 km/sec
      Solar wind density : 2.9 protons/cc
      Solar wind pressure : 0.8 nPa

      IMF : 5.3 nT
      IMF Orientation : 4.5 nT South

      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 be low. Though unusually quiet for its
      size and complexity, Region 296 has potential for a C-class flare and
      a slight chance for an M-class event. Minor C-class flares are also
      possible in Region 301.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to begin the period at unsettled to
      active levels, but should gradually decline to mostly quiet to
      unsettled levels by day two. Isolated active periods are likely on
      days two and three.

      Recennt significant solar flare activity :
      None
