      ** Aurora Watch In Effect **

      This Valentine's Day finds the Earth inside a coronal hole generated
      solar wind stream, and the solar wind speed is over the 550 km/sec
      mark. Geomagnetic storm conditions are a possibility in the higher
      latitudes, and folks should keep an eye out for aurora around the
      hours of local midnight and after. There are five sunspot regions
      currently visible on the solar disk tonight, and all on the western
      side of it. None of them appear to have any significant flare
      generating potential at this time. Look for the sunspot number to
      start coming down if no new sunspot regions appear over the next two
      or three days. The elevated solar wind speeds are expected to
      continue for at least another 48 hours, as this coronal hole is a
      pretty good sized one.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 113
      SFI : 131
      A index : 19
      K index : 4

      Solar wind speed : 556.3 km/sec
      Solar wind density : 4.1 protons/cc
      Solar wind pressure : 1.8 nPa

      IMF : 13.1 nT
      IMF Orientation : 6.3 nT North

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Radio blackouts
      reaching the R1 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 at low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at predominantly unsettled to
      active levels. Minor storm conditions are possible, especially at high
      latitudes, beginning on day one due to a large recurrent coronal hole.

      Recent significant solar flare activity :
      None
