      As last time, there isn't much to speak of this time, although sunspot
      region 837 has been growing fairly rapidly. At the present time,
      however, it doesn't look at have the magnetic complexity to generate a
      significant flare. The solar wind speed is mildly elevated and
      meandering about the 500 km/sec range. Personally, I don't think
      anything will come of it, but the folks at spaceweather.com are
      suggesting that inhabitants of northern Europe, Alaska, and Canada
      keep an eye out for aurora.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 63
      SFI : 88
      A index : 17
      K index : 2

      Solar wind speed : 514.4 km/sec
      Solar wind density : 1.7 protons/cc
      Solar wind pressure : 0.8 nPa

      IMF : 8.1 nT
      IMF Orientation : 1.3 nT North

      GOES-12 Background X-ray Flux level : A6

      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.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be mostly unsettled for the next
      24 hours (21 December) with a chance for isolated active periods.
      Quiet to unsettled levels are expected for 22 and 23 December.

      Recent significant solar flare activity :
      None
