      Little has changed since the last report, and there doesn't seem to be
      any increase in the solar wind speed do to coronal hole influence at
      this time. Sunspot region 671, near the western limb of the solar
      disk, is growing rapidly, and has an outside chance of producing an
      M-class flare before it rotates out of view. Despite the relative
      lack of activity, there have been a few great aurora pictures captured
      in Alaska, as can be seen here :
      http://science.nasa.gov/spaceweather/aurora/gallery_01sep04.htm .
      Northern autumn is the best time of year to see aurora, and that time
      is almost upon us.

      The current solad and geomagnetic conditions are :

      NOAA sunspot number : 85
      SFI : 125
      A index : 10
      K index : 1

      Solar wind speed : 367.9 km/sec
      Solar wind density : 1.8 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 3.5 nT
      IMF Orientation : 1.2 nT South

      GOES-12 Background X-ray Flux level : n/a

      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.
      There is a slight chance for an isolated M class flare.

      Geomagnetic activity forecast :
      The geomagnetic field is
      expected to be quiet to unsettled for the next three days (09-11
      September).

      Recent significant solar flare activity :
      None
