      The solar wind speed is now declining after the most recent coronal
      hole solar wind stream encounter. The solar wind speed peaked out at
      around the 600 km/sec mark. From a geomagnetic standpoint, it was
      pretty much a no-show, as a north-pointing Interplanetaty Magnetic
      Field kept a cap on any geomagnetic activity. There is another
      coronal hole that has rotated into view. Stay tuned for more
      information on that one. The sunspot number continues to slowly
      increase, and there are 5 numbered sunspot regions now visible. One
      of them, region 243, looks like it may actually have the potential for
      popping off an M-class flare. If it did, it would break a fairly long
      period of no significant flares.

      The current solar and geomnagnetic conditions are ;

      NOAA sunspot number : 128
      SFI : 148
      A index : 6
      K index : 1

      Solar wind speed : 398.3 km/sec
      Solar wind density : 2.3 protons/cc
      Solar wind pressure : 0.7 nPa

      IMF : 3.6 nT
      IMF Orientation : 1.0 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 :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be at low levels. Region 243 has a very
      slight chance of producing a low level M-class event.

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

      Recent significant solar flare activity :
      None
