      ** G-1 Geomagnetic Storm In Progress **
      ** Aurora Watch in Effect **

      Look closely at the sunspot number. You're not going to see this very
      often. No, it's not a typo. Not a single sunspot is visible on the
      Earth-facing side of the sun! Needless to say, solar activity is
      very, very quiet. So why the geomagnetic activity? That is thanks to
      a small coronal hole and a south-pointing interplanetary magnetic
      field. Skywatchers in the higher latitudes should keep an eye out for
      aurora tonight. On the heels of the small coronal hole is a larger
      one that will soon be in an Earth-pointing position. We should start
      picking up the solar wind gusts from it by the weekend.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 0
      SFI : 94
      A index : 15
      K index : 5

      Solar wind speed : 523.0 km/sec
      Solar wind density : 6.0 protons/cc
      Solar wind pressure : 2.0 nPa

      IMF : 9.4 nT
      IMF Orientation : 7.3 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 be very low. There may be a gradual
      increase in background and activity levels with the return of old
      Region 536 (latitude S11) tomorrow (28 January).

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be unsettled to active for the
      next 24 hours (28 January) as a positive polarity coronal hole is
      rotating into geoeffective position. A decline to mostly unsettled
      with possible isolated active periods is expected for the second and
      third days (29-30 January).

      Recent significant solar flare activity :
      None
