Geomagnetic Storm – More to come?

This slideshow requires JavaScript.

The solar storm of August 1st sent two CMEs toward Earth. The first one arrived yesterday, August 3rd, sparking mild but beautiful Northern Lights over Europe and North America (see below). The second CME is still en route. NOAA forecasters estimate a 35% chance of major geomagnetic storms when the cloud arrives on August 4th or 5th. High-latitude sky watchers should remain alert for auroras.

A coronal mass ejection (CME) hit Earth’s magnetic field on August 3rd at 1740 UT. The impact sparked a G2-class geomagnetic storm that lasted nearly 12 hours–time enough for auroras to spread all the way from Europe to North America. Shawn Malone of Marquette, Michigan, photographed this display over Lake Superior.

“The brightness was nice and there were quite a few purple spikes [dancing out of] the green arc below,” says Malone. “A 30 second exposure with my Canon 5D Mark II really brought out the colors.”

“Woohoo!” exclaims Canadian photographer Olivier Du Tre of Cochrane, Alberta. “I’ve been dreaming about seeing auroras since I was a boy and last night I finally did. I jumped up and down like a little kid when I saw that green stuff on my camera’s LCD screen. They beamed right through the clouds.”

With the possible arrival of a second CME on August 4th, tonight might be even better than last night. Earth’s magnetic field is still reverberating from yesterday’s CME impact, and this is sparking Northern Lights around the Arctic Circle. Peter Rosén sends this picture from Stockholm, Sweden.
