In Norway, noticed the rare azure radiance

A crack in the Earth's magnetic field, which opened February 18, is called one of the most unusual auroras over the years. In the night sky over the Lofoten Islands in Norway lit azure and turquoise lights.

The Aurora has green, sometimes red. The colors produced by oxygen when it is excited under the influence of charged particles from space. The shades of blue — a sign of nitrogen.

"After a snowfall and a strong wind the clouds cleared and within two hours the sky above the mountains shone with an amazing pale green, blue and purple lights," said photographer Matthew Steinberg.

The energy of a particle, affecting the ionized molecular nitrogen (N2+) at very high altitude (>400 km), produces a cold azure glow. Usually, lights of this type are fairly weak, but on February 18 they were extremely intense.

Then the Aurora would turn green, but it had an unusual shape. So they looked from the Norwegian tromsø.

"I had never before seen. This sparkling green bridge over the water was truly magical!" said photographer Marcus Varick, guide to polar SENIM with years of experience.
