      This Thanksgiving evening find the Earth inside of a coronal hole
      solar wind stream, and the solar wind speed is a bit elevated at
      slightly over the 500 mark. While aurora are not in the official
      forecasts, there has been a G-1 geomagnetic storm within the last 24
      hours, so at least a passing glance to the sky might be worthwhile for
      those in the higher latitudes. There are four numbered sunspot
      regions visible, but none appear to have the potential of producing a
      significant flare at this time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 61
      SFI : 109
      A index : 18
      K index : 3

      Solar wind speed : 504.0 km/sec
      Solar wind density : 1.6 protons/cc
      Solar wind pressure : 0.5 nPa

      IMF : 6.7 nT
      IMF Orientation : 4.6 nT South

      GOES-12 Background X-ray Flux level : B2

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Geomagnetic storms
      reaching the G1 level occurred.

      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 with a slight chance of an
      isolated M-class event.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled. Isolated
      active conditions are possible for 26 November as the geomagnetic
      field continues to be under the influence of the coronal hole high
      speed stream.

      Recent significant solar flare activity :
      None
