      All is relatively quiet this evening as we await the arrival of the
      next set of coronal hole solar wind gusts, which should be arriving
      sometime tomorrow. For the time being, however, the solar wind speed
      has settled into the 450 km/sec range. The current K index, oddly
      enough, is 4, which indicates an active geomagnetic field. Minor
      storm level is 5. The aurora monitors show that there might be some
      aurora visible in the higher latitudes, so take a peek at the sky if
      you're out around local midnight or after. There isn't much happening
      on the sunspot or flare front for the present time. None of the six
      sunspot regions visible currently look as if they have any flare
      generating potential, although sunspot region 274, which has just
      rotated into view, isn't in a position yet to get a decent look at it.
      The relatively large disparity between the low SFI and the higher
      sunspot number indicates that none of the sunspots currently visible
      are very energetic.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 173
      SFI : 124
      A index : 12
      K index : 4

      Solar wind speed : 450.4 km/sec
      Solar wind density : 4.5 protons/cc
      Solar wind pressure : 1.4 nPa

      IMF : 10.4 nT
      IMF Orientation : 6.4 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 persist at low levels.

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

      Recent significant solar flare activity :
      None
