Over Alaska broke out of a unique green-pink Aurora

The streams of charged particles, known in popular parlance as the "solar wind", hit our planet's magnetic field and spawned an amazing sight: over the territory of Alaska was also on fire multiple auroras.

According to Sasha Layos, the author of this picture made it around the city of Fairbanks, natural phenomenon has made her one of the strongest impressions in my life.

Night temperature that day stayed at around -40 degrees, so, according to the Layos, the majority of local residents during the spectacle were more cautious and stayed home.

In addition to Sasha, Northern lights over Fairbanks was inspired by another photographer — Thomas McCarthy. He also noted that major part of green atmospheric glow was fringed with a pink stripe. It is also called "nitrogen fringe".

The vast amount of Northern lights has a green tint. It is the color of light the oxygen particles are affected by the solar wind flow at altitudes of 100-300 km. The pink color is caused when charged particles from space reach the lower layers of the atmosphere and excite the nitrogen molecules, are located below the 100-kilometer mark.
