Jonathan Tucker photographed this display over Whitehorse in the Yukon Territories during the early hours of Sept. 3rd:

As expected, a coronal mass ejection hit Earth on Sept. 3rd at approximately 1200 UT (5 am PDT) in Lofoten, Norway. The impact induced significant ground currents in the soil of northern Scandinavia and sparked bright auroras around the Arctic Circle.

A moderate geomagnetic storm is underway.


CHANCE OF FLARES: Sunspot AR1560 has more than quadrupled in size since August 30th, and now the fast growing active region is directly facing our planet: movie. NOAA forecasters estimate a 40% chance of M-class solar fares during the next 48 hours. Solar Flare alerts: text, phone.

MAGNIFICENT ERUPTION: A filament of magnetism curling around the sun’s southeastern limb erupted on August 31st, producing a coronal mass ejection (CME), a C8-class solar flare, and one of the most beautiful movies ever recorded by NASA’s Solar Dynamics Observatory:

The explosion hurled a CME away from the sun traveling faster than 500 km/s (1.1 million mph). The cloud is not heading directly toward Earth, but it could deliver a glancing blow to our planet’s magnetic field on or about September 3rd. This date is preliminary and may be changed in response to more data from coronagraphs on the Solar and Heliospheric Observatory (SOHO). Stay tuned.
