A geomagnetic storm that began on Sept. 3rd when a coronal mass ejection (CME) hit Earth's magnetic field is subsiding now. The impact at 1200 UT induced significant ground currents in the soil of northern Scandinavia and sparked bright auroras around the Arctic Circle
GEOMAGNETIC STORM ALERT: A geomagnetic storm is in progress in the wake of a double CME impact on June 16th. The hit, which strongly compressed Earth's magnetic field, lit up both poles with bright auroras. Stephen Voss sent this photo from Southland, New Zealand:
RED AURORAS: On October 2nd, a CME hit Earth's magnetic field, sparking a G2-class geomagnetic storm. Sky watchers on both ends of the Earth saw auroras; many of the lights were rare shades of red. Minoru Yoneto photographed this example from Queenstown, New Zealand.

SPOOKY AURORAS: High-latitude sky watchers should be alert for auroras on Halloween. A CME is expected to hit Earth's magnetic field on Oct. 31st, possibly sparking polar geomagnetic storms. In northern Norway, the show got started early with this display on Oct. 30th.
A geomagnetic storm is in progress as Earth passes through the wake of a CME that arrived on Oct. 8th. Reports of auroras are coming in from across Canada and all the northern-tier US states. Beth Allan sends this picture from Fort Saskatchewan, Alberta.
