These aurora photogaphs were taken at late twilight, (approx. 5 PM Alaska time). At twilight is when the blue often shows up in the aurora color spectrum. Clouds were a problem for much of the night, which was a bummer, as I could see only parts of the continual displays.

A beautiful display last evening, lots of movement and pulsations, nice flowing curtains and some beautiful red beams, faded out after about 1.5 hrs.

The aurora mostly appeared as a green/red glow on the horizon, with occasional green pillars and ribbons shooting up 20 or so degrees up the sky. The tree shadows on the barn in this shot are cast by the stray light of Lincoln, Nebraska reflecting off a large cloud over the city 15 miles south.

Skies cleared out for the most part in Scottsbluff, NE on Thursday night to help see a descent display of the Northern Lights. The first set of aurora photos were taken about 20 miles north of Scottsbluff, NE (around 9:30pm MT). The second set of aurora photos were taken between 11pm - 1:30am MT, around Scottsbluff National Monument. The colors consisted of a green glow along the horizon with a redish/purplish glow above with streaks shooting upwards. For a while the aurora subsided but then it started up again with some nice focused streaks upward. Finally, auroras in Nebraska again!

After driving over 250 km in search some clear skies. We finally found the G4. Although not a lot of colour at our local it was a great show. The one with the Big Dipper is my favourite from the morning.

I had read on Space Weather that auroras might be possible. I took to the fields around 9:00 PM and was able to view faint activity. It is not often we get to see displays in Connecticut.

Photo details: Canon EOS-1D, Mark II N. ISO 800, shutter at 30 secs.

I went outside to retrieve something from my car and I looked out to the north as a faint light in the distance caught my attention, I grabbed my camera and soon the auroras lit up the entire sky as the clouds started to clear. Photo details: Olympus Evolt E-500 14mm f 3.5 1600 ASA 60s exposure
