      ** Aurora Watch In Effect **

      The Earth remains inside of the high speed solar wind stream tonight,
      and more geomagnetic storm conditions have been observed. The aurora
      watch is still in effect. Starting tomorrow, the solar wind speed
      should start backing off from its current level, and we'll see an
      accompanying decline in the degree of geomagnetic activity. However,
      don't be surprised if there are some G-1 geomagnetic storm conditions
      observed from time to time for the next 24 hours. Currently, there
      are two numbered sunspot regions visible. Neither looks to have the
      potential for generating a significant flare at the present time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 40
      SFI : 88
      A index : 27
      K index : 4

      Solar wind speed : 744.3 km/sec
      Solar wind density : 0.6 protons/cc
      Solar wind pressure : 0.7

      IMF : 6.0 nT
      IMF Orientation : 3.1 nT North

      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 :
      Space weather for the next 24 hours is expected to be minor.
      Geomagnetic storms reaching the G1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be very low to low.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at unsettled to active levels
      for 14-15 Dec. Quiet to unsettled conditions are expected on 16 Dec.

      Recent significant solar flare activity :
      None
