      ** Aurora Watch In Effect **

      As per the predictions, the Earth has moved inside of a high speed
      colar wind stream coming from a large coronal hole. G-1 geomagnetic
      storm conditions have been observed within the last 24 hours, and an
      aurora watch in now in effect. Skywatchers, especially those in the
      higher latitudes, should keep an eye out for aurora. The current
      active conditions and elevated solar wind speeds are expected to last
      for at least the next three days. Sunspot region 564, the source of
      the two big flares a few days ago, is now approaching the western limb
      of the solar disk. While it has been relatively quiet since its
      aforementioned outburst, it still have the potential for generating
      another big flare.

      The current solar and geomagnetic conditions are :

      NOA sunspot number : 104
      SFI : 116
      A index : 21
      K index : 3

      Solar wind speed : 654.6 km/sec
      Solar wind density : 0.5 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 6.8 nT
      IMF Orientation : 4.2 nT South

      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. Radio
      blackouts reaching the R1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be mostly low with a chance for isolated
      moderate. There remains a good potential for Region 564 to produce a
      major flare.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at unsettled to active levels
      with a fair chance for periods of minor storming through 2 March, due
      to the influence of a high-speed solar wind stream.

      Recent significant solar flare activity :
      None
