      All remains calm this Thanksgiving Day, and the solar wind speed has
      slowed down some, as anticipated. Sunspot region 508 produced the
      only notable activity, that being a long duration C9.6 flare.
      Curiously, the sun is peppered with sunspots this evening, with seven
      numbered sunspot regions being visible. That's more than you might
      expect to see at this time in the sunspot cycle, although spikes of
      activity are certainly possible at any time. Of the group, sunspot
      region 508 appears to have the best chance to produce a significant
      flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 175
      SFI : 175
      A index : 8
      K index : 2

      Solar wind speed : 415.1 km/sec
      Solar wind density : 3.1 protons/cc
      Solar wind pressure : 0.5 nPa

      IMF : 5.6 nT
      IMF Orientation : 1.1 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 :
      Space weather for the next 24 hours is expected to be minor. Radio
      blackouts reaching the R1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be low to moderate. M-class flares
      remain possible from Region 507 and Region 508.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled, with
      isolated periods of active conditions in higher latitudes on 29-30
      November.

      Recent significant solar flare activity :
      None
