      ** Aurora Watch In Effect **

      The high speed solar wind stream still persists this evening, and the
      solar wind speed is over the 600 km/sec mark. A G1-class geomagnetic
      storm was in force for much of the 26th and 27th. See this link for a
      nice picture of an aurora display taken in Calgary, Alberta in the
      pre-dawn hours of the 26th.

      Within the next day or two, the Earth should exit the high speed solar
      wind stream, and conditions will return to normal. Sunspot regions
      9661 and 9663 have the potential of generating M-class flares, with an
      M2-class flare occurring Tuesday.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 218
      SFI : 186
      A index : 12
      K index : 3

      Solar wind speed : 602.3 km/sec
      Solar wind density : 1.5 protons/cc
      Solar wind pressure : 0.8 nPa

      IMF : 5.2 nT
      IMF Orientation : 0.1 nT South

      Conditions for the last 24 hours :
      No space weather storms were observed for the past 24 hours.

      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 9961 and 9963
      have the potential for isolated M-class events.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels.
      Isolated active conditions are possible on day one of the forecast
      period.

      Recent significant solar flare activity :
      27-May-2002 1810Z M2.0
