Hunting for the northern lights in the village Teriberka

Northern Lights - glow of the upper layers of the atmosphere of the planets. Today we will try to find it in the village of Teriberka on the Kola Peninsula.

Teriberka is located on the Kola Peninsula directly on the shores of the Barents Sea, in the tundra zone. The climate is subarctic.

The intensity of the radiance grew with every minute and now its reflection could already be seen in the waters of the bay.

When observed from the surface of the Earth, the aurora is manifested in the form of a general rapidly changing glow of the sky or moving rays, strips, crowns, "curtains." The duration of auroras varies from tens of minutes to several days.

Northern lights in spring and autumn appear much more often than in winter and summer. The peak of frequency falls on the periods closest to the spring and autumn equinoxes.

During the aurora, a huge amount of energy is released in a short time. So, for one of the disturbances registered in 2007, 5 · 1014 joules were allocated, approximately the same as during the earthquake with a magnitude of 5.5.

The aurora spectrum varies with altitude. Depending on the emission lines prevailing in the auroral spectrum, auroras are divided into two types: auroral auroras of type A with predominance of atomic lines and auroras of type B at relatively low altitudes (80-90 km).

The most widespread color of the northern lights is green, it is created as a result of the collision of electrons with oxygen atoms at an altitude below 400 km. Nitrogen molecules in the lower layers of the ionosphere create red light. And at the very top of the ionosphere, nitrogen molecules emit a rich violet color, but it is usually too dim, and it can not be seen from the surface of the Earth. Transfusions of these flowers and give birth to unusual, fantastic coloring fluttering pictures.

The northern lights are not only on Earth, they were seen both on Venus and on Mars. Uranus and Neptune also featured auroras. And the magnetic fields of the giant planets of the solar system are much stronger than the Earth's magnetic field, which causes a greater scale of the auroras of these planets in comparison with the polar auroras of the Earth. So, the highest in the solar system (1200 km) is the northern lights of Saturn.

Predicting the phenomenon is almost impossible; this fact always plagued travelers who want to see with their own eyes the "dancing of spirits". However, since the probability of the appearance of radiance depends directly on the solar activity.
So if you want to see the northern lights in Russia, it's best to choose the Kola Peninsula.
