Space Weather News for Aug. 31, 2014

   Aurora season is now fully underway around the Arctic circle.  With the end of   
   northern summer approaching, dancing green lights are beaming through the   
   deepening polar twilight on a regular basis. Unlike lower latitudes, the   
   Arctic does not require a full-fledged geomagnetic storm for aurora   
   sightings.  Check the latest images on the front page of http://

   Meanwhile, another polar phenomenon is on the wane: noctilucent clouds   
   (NLCs).  Data from NASA's AIM spacecraft suggest that the northern summer   
   season for NLCs ended on or about August 26th.  The "noctilucent daisy" shown   
   on http://spaceweather.com will probably remain blank until November, when NLC   
   activity shifts to the southern hemisphere.  NLCs are a summertime phenomenon   
   and they switch back and forth between the hemispheres accordingly.  Stay   
   tuned for more electric blue ... in a few months.
