AURORA BOREALIS

An aurora sometimes referred to as polar lights or northern lights, is a natural light display in the Earth's sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.

Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost.

The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

THE CACHE

The cache is located in place, which is good to view aurora. Here you can find some really interesting points to make a photo of northern lights over the narrow bay with city lights, mountains or the road, where car lights can cause really unexpected effects. Because of small field depression nearby the road, it's also easy to make a picture of your shape in the foreground. Below I present some photos taken here.

The cache is located at the bigger stone, north of the road 50.
