      ** Aurora Watch In Effect **

      The Earth should soon be entering a coronal hole generated high speed
      solar wind stream, and an aurora watch is in effect for that reason.
      We should start seeing the effects either Sunday or Monday. A strong
      south tilt to the Interplanetary Magnetic Field has caused the
      geomagnetic field to be somewhat active today, actually reaching the
      G-1 geomagnetic storm level at one point. If the IMF retains its
      south-pointing orientation when the high-speed solar wind hits, things
      could be quite interesting. The are several sunspot regions visible
      on the solar disk. Sunspot region 177 looks like it is the only one
      to have any flare generating potential for the time being.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 177
      SFI : 165
      A index : 22
      K index : 2

      Solar wind speed : 484.6 km/sec
      Solar wind density : 5.2 protons/cc
      Solar wind pressure : 2.3 nPa

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

      IMF : 10.5 nT
      IMF Orientation : 9.0 nT South

      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. Region 177 has the
      potential to produce an isolated M-class event.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be predominately unsettled to
      active for the next three days in response to a recurring coronal
      hole.

      Recent significant solar flare activity :
      None
