Widespread display of aurora's erupted last Friday
A widespread display of auroras erupted late Friday, Aug. 5th, when a double-CME hit Earth's magnetic field and sparked a G4-category geomagnetic storm. "It was the most impressive display I've seen in years," reports Lance Taylor of Edmonton, Alberta. "From 10:00 PM on Friday to 3:00 AM on Saturday, the sky was pulsing from horizon to horizon in every direction." He took this picture during the most intense phase of the storm:

The show was not restricted to Canada. Northern Lights spilled across the border into the United States as far south as Utah, Colorado, and Nebraska. (Note: The faint red lights photographed in Nebraska are typical of low-latitude auroras during major geomagnetic storms.) Observers in Europe as far south as England, Germany and Poland also witnessed a fine display. Browse the gallery for more examples.

STRONG SOLAR ACTIVITY: Sunspot 1283 is crackling with solar flares. Yesterday, Sept. 6th, the active region produced an M5.3-class eruption at 0150 UT followed by a X2.1-class event at 2220 UT. NASA's Solar Dynamics Observatory recorded this extreme UV flash from the X-flare:

The flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around our planet. Moreover, the two eruptions hurled clouds of plasma (CMEs) in our general direction. A preliminary analysis of SOHO and STEREO imagery suggests that the CMEs could sail substantially north of Earth, delivering a glancing blow to Earth's magnetic field as they pass. ETA: Sept. 8-10. Stay tuned for updates
