:-D Aurora video and info courtesy of NASAs spaceweather AURORAS IN MOTION: As predicted, a pair of CMEs hit Earths magnetic field in quick succession on Sept. 11th and 12th. The result was a G3-class geomagnetic storm, the most intense of the year so far. Around the Arctic Circle, the storm sparked aurora displays that will never be forgotten by the people who were lucky enough to witness the event, reports tour guide Chad Blakley of Abisko, Sweden. This short film is for everyone else. At the peak of the storm, observers in Scandinavia witnessed stunning coronas and even a rare aurora-rainbow ensemble. A hint of auroras were even photographed in Arizona. The storm is subsiding now. Nevertheless, high-latitude sky watchers should remain alert for auroras. NOAA forecasters estimate a 50% chance of additional polar geomagetic activity on Sept. 14th as Earth passes through the wake of the double CME. vimeo/106051784 spaceweather/
