      ** Aurora Watch In Effect **

      It's no secret that the Earth has been inside of a high speed solar
      wind stream for about a week now. The result has been some beautiful
      aorora displays seen over the last several nights in several locations
      in the northern US and Canada, as can be seen here :
      http://science.nasa.gov/spaceweather/aurora/gallery_01jul03_page2.html
      The Earth now exiting the stream, and the solar wind speed is slowly
      dropping from the near-800 km/sec level it was at for the last couple
      of days. The speed remains elevated, however, and there's still a
      chance of some more aurora tonight. There's also been a bit of flare
      activity, with an M-1 class flare coming late on the 2nd. The solar
      wind speed should steadily decline over the next three days, but it
      may not last for long. There's another coronal hole that's rotating
      into position, and we could see some effects from it around the middle
      of the week. Stay tuned!

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 95
      SFI : 111
      A index : 24
      K index : 3

      Solar wind speed : 658.1 km/sec
      Solar wind density : 1.1 protons/cc
      Solar wind pressure : 0.7 nPa

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Radio blackouts
      reaching the R1 level occurred.

      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 remain low. Region 424 (S18E64)
      continues to pose the greatest threat with only a slight chance for
      M-class x-ray flare activity.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at unsettled to active levels.
      The coronal hole is in the process of moving out of geoeffective
      range, and no recurrent solar features should impact earth for the
      next three days.

      Recent significant solar flare activity :
