Aurora Borealis

It’s finally getting dark enough at night to see the Northern Lights again. They are also known as the Aurora Borealis. All images were taken at Four Mile Lake near Fort Smith, Northwest Territories, between 12:30 and 2:30 in the morning.

From www.northernlightscentre.ca: The Northern Lights are actually the result of collisions between gaseous particles in the Earth’s atmosphere with charged particles released from the sun’s atmosphere. Variations in colour are due to the type of gas particles that are colliding. The most common auroral color, a pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora.
