      ** Aurora Watch In Effect **

      The solar wind speed is up to the 600 km/sec mark tonight as the Earth
      slides into a coronal hole high speed solar wind stream. Although
      geomagnetic activity has remained low so far, that could change at any
      time. Therefore, an aurora watch is in effect, especially for the
      higher latitudes. The sunspot number, after languishing in the 50's
      range for several days, has increased up to over 100 with the
      emergence of a new sunspot region. That sunspot region, region 242,
      has at least a remote chance for kicking off an M-class flare. The
      high speed solar wind speeds should persist for another 24 hours or
      so, and then begin to wane.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 108
      SFI : 138
      A index : 15
      K index : 3

      Solar wind speed : 602.0 km/sec
      Solar wind density : 2.2 protons/cc
      Solar wind pressure : 1.1 nPa

      IMF : 4.9 nT
      IMF Orientation : 2.3 nT North

      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 at low levels. A very slight chance
      of an isolated low level M-class flare is possible from Region 242.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at predominantly unsettled to
      active levels on day one of the forecast period due to high speed
      stream coronal hole. Days two and three should see a return to quiet
      to unsettled conditions as the geo-effective coronal hole wanes.

      Recent significant solar flare activity :
      None
