Aurora vs Junsele District

Informations

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere).

The resulting ionization and excitation of atmospheric constituents emit 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.

Sollefteå Municipality (Swedish: Sollefteå kommun) is a Swedish municipality in Västernorrland County. Its seat is located in Sollefteå. The former City of Sollefteå (instituted in 1917) was amalgamated with the surrounding entities in 1974 to form the present municipality. It consists of fifteen original (1863) units.

Historically, the name is found as early as the 13th century in the form of the Latin De Solatum, which would translate to "The Sunny Place" (or so). A market place was situated here in 1602 on Royal permission. The city's coat of arms depicts a Black Grouse.
