      The Earth remains inside a coronal hole generated high speed solar
      wind stream this evening, as it has been in for the last 3 days. The
      solar wind speed and density has remained elevated, although it has
      not caused much in the way of geomagnetic activity. None of the
      relatively few sunspot regions visible this evening look like they
      have much in the way of flare generating potential, although there was
      a modest M-class flare earlier today.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 113
      SFI : 153
      A index : 8
      K index : 2

      Solar wind speed : 409.3 km/sec
      Solar wind density : 5.6 protons/cc
      Solar wind pressure : 1.3 nPa

      IMF : 7.9 nT
      IMF Orientation : 3.6 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 :
      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. A general trend of
      increased activity is expected as the east limb regions rotate onto
      the disk.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled.

      Recent significant solar flare activity :
