      ** Aurora Watch In Effect **

      G-1 geomagnetic storm conditions are expected from time to time as the
      Earth drifts though a high speed solar wind stream. See this link for
      aurora that were photographed near Quebec City, Canada, Saturday night
      : http://science.nasa.gov/spaceweather/aurora/gallery_01jun03.html .
      This summer has been rather unusual for aurora. Typically, although
      nobody understand completely why, the equinoxes seem to be much better
      times for aurora watching than the solstices. However, this summer
      has been the exception, as there have been numerous aurora sightings
      during May and June. Sunspot region 386 has been losing a bit of its
      magnetic punch and shrinking in size, and the background X-Ray flux
      has been slowly dropping accordingly. However. region 386 is still
      capable of producing an M-class flare. Expect the high speed solar
      wind to continue for at least the next 24 hours.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 94
      SFI : 110
      A index : 15
      K index : 3

      Solar wind speed : 530.1 km/sec
      Solar wind density : 2.3 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 6.8 nT
      IMF Orientation : 4.5 nT North

      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 continue at low levels. There is a small
      chance for an isolated low M-class flare from Regions 386, 387 and 388.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to continue at unsettled to active
      levels due to coronal hole high speed flow.

      Recent significant solar flare activity :
      None
