Those Aren’t Northern Lights

at

THESE are Northern Lights.

A spectacular aurora captured outside Östersund in Sweden in 2016. To wit:

Six photographic fields were merged to create the featured panorama spanning almost 180 degrees. Particularly striking aspects of this aurora include its sweeping arc-like shape and its stark definition. Lake Storsjön is seen in the foreground, while several familiar constellations and the star Polaris are visible through the aurora, far in the background. Coincidently, the aurora appears to avoid the Moon visible on the lower left. The aurora appeared a day after a large hole opened in the Sun’s corona allowing particularly energetic particles to flow out into the Solar System. The green colour of the aurora is caused by oxygen atoms recombining with ambient electrons high in the Earth’s atmosphere.

    Stunning! I had rarely seen the aurora, but it always leaves me marvelling at the beauty.
