  Summary: A coronal mass ejection (CME) hit Earth's magnetic field on Sept. 9th, sparking a (Kp=7) geomagnetic storm. Northern Lights were sighted in the United States as far south as Maine, Michigan, Vermont and Washington. Another CME struck on Sept. 17th, sparking a Kp=6 storm. The biggest CME strike of the month occured on Sept. 26th. A severe (Kp=8) geomagnetic storm ignited auroras over both hemispheres. (See also August 2011.)

Storm indeed! Tonight on the island of Kvaløya outside Tromsø some of the most amazing auroras that I have ever seen could be glimpsed between the rain-clouds - I halfway expected to see some aurora-rainbow :-). The colours were absolutely stunning with purple and deep blood-red in addition to the green. Here are some shots from a corona time-lapse sequence from tonight, a night I will never forget! Nikon D3, AF-S Nikkor 14-24 mm f/2,8 at f/3,5, ISO 800-1000, exposure 3-20 secs.

Tallest bands of aurora ever seen up here which started as soon as it got dark. It was hard to keep from giggling during the awesome hour long show.

These are DMSP Satellite images from September 26 through 27, 2011, over the Northern Polar regions. The primary sensor was the Operational Linscan System (OLS) onboard the DMSP F18 in Polar Orbit. The imagery includes night time visual imagery and Visual/Infrared Multispectral Imagery (MSI).

The night was wonderful but I have never seen such Northern Lights show as this. The sky bursted into white, pink, red and green colors. It was just magnificent. Camera: Canon EOS 5D Mark II. Lens: Canon 14 mm f/2.8L II USM. ISO 1600 and 1s exposure.

The first good show of the season here at Summit Station, Greenland. On top of the Greenland ice sheet we finally had clear, cool temperatures.... and adequate darkness. -35c/-31f. The colors changed with time and the reddish colors occurred with tiny ice crystals in the air. I'm not sure if that had anything to do with it though! Bands stretched across the ice sheet.

Life In a Northern Town ----------------------- After watching the solar storm yesterday I was on high alert for Aurora's. Sure enough, around 9pm I saw some flecks of green pop up. A quick drive to Selkirk State Park at about 9:30pm EST and I had just enough time to get 4 or 5 shots before the clouds moved in. I wish it had lasted longer... but cant be greedy. As a bonus we saw a meteorite coming down. This one clearly made landfall. It was slow moving, with a burning tail and got bright and bigger as it shot over the trees to the north. It was an incredible sight. Too bad the camera was busy exposing the Northern Lights.
