      All remains quiet tonight as the solar wind speed is languishing
      around the 300 km/sec mark. It would seem that the most recent
      expected coronal hole encounter with its associated high speed solar
      wind is a no-show. Therefore, I don't see anything on the immediate
      horizon that's likely to cause any significant activity. Sunspot
      region 464 is approaching the western limb of the solar disk, and
      while it still has the potential of creating an M-class flare, so far
      it's been relatively quiet. The background X-ray flux is steadily
      rising, however, so stay tuned.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 116
      SFI : 133
      A index : 4
      K index : 3

      Solar wind speed : 283.1 km/sec
      Solar wind density : 4.7 protons/cc
      Solar wind pressure : 0.6 nPa

      IMF : 5.8 nT
      IMF Orientation : 2.9 nT South

      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 low to moderate. Region 464 has the
      potential for C- and M-class flares. Region 471 may also produce C-
      and isolated M-class flares.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to remain at quiet levels. There
      exists an isolated chance of unsettled to active conditions from a CME
      arrival related to an erupting filament on 28 Sep.

      Recent significant solar flare activity :
      None
