Northern Lights - Amazing images

The beautiful images were taken by Linda Drake, a photographer who braved temperatures of minus 20 degrees to capture them.




"Most people travel to Churchill in Manitoba to photograph the polar bears coming out of hibernation in February and March, but I like to set up camp and wait each evening for the dancing lights and nature's most breathtaking show," said the San Luis Obisto based photographer.
"It never ceases to amaze me how grand the shows of colour are and how each one differs so wildly from the last.
"Hopefully in these pictures I have managed to capture the beauty that has transfixed me."

Usually catching the light shows between midnight and two in the morning, Ms Drake uses a variety of different camera exposure times to photograph the aurora.

"Sometimes I leave the lens open for two to three seconds and on other occasions go for 30 seconds to one whole minute," she said.
"The longest display of the northern lights that I have seen has lasted for up to two hours."

Caused by photon emissions in the upper ionosphere around 50 miles up, the light shows are the result of ionised nitrogen atoms becoming excited by solar wind particles funneling through the Earth's atmosphere.
