      Despite the absence of anything major, G-2 geomagnetic storm
      conditions and aurora were the order of business Friday night when an
      elevated solar wind speed combined with a south-pointing
      interplanetary magnetic field to touch off the action. Some quite
      beautiful aurora were photographed across Canada, northern Europe, and
      the northern US, as can be seen here.

      As of now, things have calmed down some for the time being. A new
      sunspot region, region 718, is rotating into view over the eastern
      limb of the solar disk, but it doesn't look to have any real
      flare-generating potential for now. A coronal hole located in the
      sun's northern hemisphere that might send some solar wind gusts our
      way which would arrive on or about the 18th, although the coronal is
      probably located too far north for it to be a direct hit.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 34
      SFI : 89
      A index : 20
      K index : 1

      Solar wind speed : 452.1 km/sec
      Solar wind density : 1.9 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 8.3 nT
      IMF Orientation : 4.6 nT North

      GOES-12 Background X-ray Flux level : A7

      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 very low to low. Isolated C-class
      flare activity is possible from the regions near the southeast limb.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to active levels. The
      solar wind transients should abate by the end of 08 Jan, and have
      little impact on the geomagnetic field for 09 through 11 Jan.

      Recent significant solar flare activity :
      None
