      All is fairly quiet this evening. Suspot region 119 looks like it has
      the potential to fire off a big flare, but it has been quiet so far.
      Its going to have to hurry if it wants to do anything, as it is just
      about to rotate over the western limb of the solar disk. The eastern
      half of the solar disk is just about void of sunspots right now, so we
      could see the sunspot numbers drop pretty soon. Sunspot region 132 is
      growing rapidly and merits watching. A small coronal hole is rotating
      into view, and could be a factor later on in the week.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 209
      SFI : 154
      A index : 3
      K index : 1

      Solar wind speed : 388.3 km/sec
      Solar wind density : 0.6 protons/cc
      Solar wind pressure : 0.1 nPa

      IMF : 8.2 nT
      IMF Orientation : 5.5 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 activity is
      possible in Region 119 and, if growth continues, Region 132.

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

      Recent significant solar flare activity :
      None
