Prior Lake vs Aurora

Informations

Prior Lake (Dakota: Bdé Mayá Thó) is an exurban city 20 miles (32 km) southwest of Minneapolis seated next to Savage and Shakopee in Scott County in the state of Minnesota. Surrounding the shores of Lower and Upper Prior Lake, the city lies south of the Minnesota River in an area known as RiverSouth and establishes the urban fringe of the south-southwest portion of Minneapolis-St. Paul, the sixteenth largest metropolitan area in the United States.

The population of Prior Lake was 22,796 at the 2010 census.Prior Lake was first incorporated as a village in 1891. Prior Lake is one of the oldest cities in the south metro area. The city's modern rapid growth is due in part to the ease of access for commuters to the rest of the region, via the upgraded State Highway 13.

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.
