Auroras in Alaska

GEOMAGNETIC STORM: A solar wind stream hit Earth's magnetic field on March 1st, sparking a day-long geomagnetic storm and bright auroras around the Arctic Circle. NASA space physicist James Spann photographed the display from Poker Flat, Alaska, where he is attending a scientific conference to study (you guessed it) auroras. Spann's image is posted in Sun Stuff Topic

Image taken:  Mar. 1, 2011
 
Location:        Wasilla, Alaska.
 
Details:          "This was one of the brighter displays I've seen, but not very colorful. As you can see in my image, the display was mostly a bluish-white. I did manage to catch an accidental visitor in one image (lights4), but I don't know if it's a satellite or what...could it be the Nanosail? The display reached from horizon to horizon (from the north to the southeast). "

APRIL AURORAS: According to the space weather forecast, geomagnetic storms were unlikely on April 1st. It would've been foolish to go out looking for Northern Lights. Warren Gammel of Fairbanks, Alaska, decided to check the skies anyway, and this is what he saw.
"I didn't expect to see too much when I went out at 2 a.m. on April 1st, but the auroras were fairly strong," he says. "I took these pictures using a Canon T1i with a Pelang 8mm fisheye lens."

The display was caused by a minor but effective solar wind stream that arrived during the early hours of April 1st. The impact sparked bright lights across the Arctic realm of North America.

ARCTIC AURORAS: A fast-moving (~550 km/s) stream of solar wind is buffeting Earth's magnetic field, sparking auroras around the Arctic Circle. In Alaska, the display was bright enough to see in full moonlight.

"Who says you can't photograph auroras under the full moon?" says Ronn Murray who took the picture from Fairbanks. "The very bright moon illuminated the landscape as the beautiful Northern Lights danced overhead."

NOAA forecasters estimate a 35% chance of polar geomagnetic storms tonight as the solar wind continues to blow

Note from Yowbarb: Happy New Year... and here is the link to the Spaceweather site Aurora Photo Gallery.

Tonight, most likely around the Arctic Circle, someone somewhere will see the last auroras of 2014. Earth's polar caps are aglow with bright Northern Lights as a fast-moving stream of solar wind buffets our planet's magnetic field. NOAA forecasters estimate a 45% chance of polar geomagnetic storms on New Year's Eve.

Taken by Sacha Layos on November 19, 2015 @ Fairbanks, AK

NORTHERN LIGHTS: Astronomers have discovered a planet with white trees and green skies. It's Earth. Sacha Layos photographed the strange landscape last night in Fairbanks, Alaska.

The auroras appeared on Nov. 19th after a CME sideswiped Earth's magnetic field, turning skies green over Alaska, Iceland, Scotland, and Sweden.

There was one more color: blue--as in "blue fingertips." Layos explains: "The temperature bottomed out at -25F where I was. Despite the extreme cold, however, it was a great show. What a welcome sight!"

CME effects are subsiding on Nov. 20th, and NOAA forecasters have downgraded the chance of a geomagnetic storm today to only 25%
