      While the solar wind speed is still elevated due to coronal hole
      effects, it is beginning to slack off, and should continue to do so
      over the next couple of days as the most recent coronal hole rotates
      out of view. Beyond that, with no additional coronal holes coming
      into view for the time being, there isn't much happening. There are
      only two numbered sunspot regions visible tonight, although one of
      them, sunspot regiuon 431, has grown quickly. The background X-ray
      flux has risen rather dramatically over the last two days, and by the
      way it was rising, I would've though we would have seen a good M-class
      flare by now. That isn't the case, however, although region 431
      definitely has the potential of producing a significant flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 108
      SFI : 130
      A index : 19
      K index : 3

      Solar wind speed : 546.2 km/sec
      Solar wind density : 4.3 protons/cc
      Solar wind pressure : 1.9 nPa

      IMF : 6.8 nT
      IMF Orientation : 4.5 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 :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be at low to moderate levels. Region 431
      remains capable of producing M-class flare activity.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to active levels
      throughout the interval. A brief geoeffective high speed coronal hole
      stream should make way for active conditions on the first two days of
      the forecast period, returning to predominantly quiet to unsettled
      levels on day three of the period.

      Recent significant solar flare activity :
      None
