      The Earth remains inside a high speed, coronal hole generated solar
      wind stream, although to this point it doesn't seem to be causing any
      geomagnetic activity to speak of. Sunspot region 9885 has grown
      dramatically over the last few days, and now appears to have the
      potential for generating a major flare. Actually, regions 9885, 9886,
      and 9887 have sort of merged together to form one big sunspot group.
      This area certainly bears watching in the days ahead as it approaches
      the sun's central meridian.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 189
      SFI : 207
      A index : 13
      K index : 2

      Solar wind speed : 682.9 km/sec
      Solar wind density : 1.7 protons/cc
      Solar wind pressure : 1.2 nPa

      IMF : 5.5 nT
      IMF Orientation : 1.3 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 :
      Space weather for the next 24 hours is expected to be minor. Radio
      blackouts reaching the R1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be low to moderate. M-class flares are
      possible in Regions 9885, 9886, and 9887.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to remain at quiet to active levels
      for the next 24 hours becoming quiet to unsettled by the end of the
      forecast period.

      Recent significant solar flare activity :
