Man films spectacular video of Northern Lights over Sweden

Videographer Chad Blakley shot his Feb 16 time-lapse sequence from Abisko National Park on the northern edge of Sweden, reported Reuters.

"I have spent countless nights out under the northern lights but I can say with 100 per cent certainty that the display that we witnessed last night was the most spectacular red corona I have ever had the pleasure of sharing with my guests," he said.

According to Reuters, Auroras occur when charged particles emitted by the sun during flare activity reach Earth's atmosphere and collide with its gases.

The most common colour, green, is produced by a collision of particles with oxygen molecules at an altitude of about 60 miles (97 km) above Earth.

At 200 miles (320 km), those molecules produce a rare, red aurora, while nitrogen produces blue lights.

Blakley, whose company, Lights Over Lapland, offers aurora photo expeditions to the park, says he hopes his footage will inspire interest from amateur photographers.
