      ** Aurora Watch In Effect **

      Yep, it's baaaaaaaaack! The coronal hole solar wind stream has
      arrived, pushing the solar wind speed well over the 600 km/sec mark.
      The Interplanetary Magnetic Field can't seem to make up its mind which
      way it wants to be oriented. It was pointing pretty strongly south
      for awhile, but now it has taken on a weak north-pointing orientation.
      If it resumes the south orientation, conditions should be right for
      some good aurora displays. There are only three numbered sunspot
      regions visible now, and two of those are soon to rotate out of view
      over the western limb of the solar disk. Unless some new sunspot
      regions come into view, the sunspot number could drop very low indeed.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 62
      SFI : 126
      A index : 14
      K index : 3

      Solar wind speed : 565.8 km/sec
      Solar wind density : 4.9 protons/cc
      Solar wind pressure : 3.2 nPa

      IMF : 14.6 nT
      IMF Orientation : 0.7 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 be low for the next three days.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be mostly active for the next two
      days in response to the high speed solar wind stream associated with a
      30 degree wide solar coronal hole. Conditions should subside slightly
      to unsettled to active levels by the third day.

      Recent significant solar flare activity :
      None
