      ** Aurora Watch In Effect **

      The Earth is still inside of a coronal hole high speed solar wind
      stream, and the solar wind speed is over 700 km/sec. An aurora watch
      remains in effect. Skywatchers in the higher latitudes should keep an
      eye out for aurora. The current conditions are expected to last for
      about another 48 hours before settling down. Only two numbered
      sunspot regions are visible on the solar disk, and neither appears to
      have the potential to generate a significant flare at the present time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 64
      SFI : 104
      A index : 17
      K index : 4

      Solar wind speed : 719.7 km/sec
      Solar wind density : 0.6 protons/cc
      Solar wind pressure : 0.5 nPa

      IMF : 4.7 nT
      IMF Orientation : 1.4 nT South

      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. There is a
      small chance for a C-class flare from Region 554.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to active with isolated
      minor storm periods at high latitudes. The coronal hole high speed
      stream in effect now is expected to continue through 16 February.
      Predominantly quiet to unsettled levels with isolated active periods
      are expected on 17 February.

      Recent significant solar flare activity :
      None
