Aurora vs Grande Prairie

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.

Grande Prairie is a city in northwest Alberta, Canada within the southern portion of an area known as Peace River Country. It is located at the intersection of Highway 43 (part of the CANAMEX Corridor) and Highway 40 (the Bighorn Highway), approximately 456 km (283 mi) northwest of Edmonton. The city is surrounded by the County of Grande Prairie No. 1. Grande Prairie was the seventh-largest city in Alberta in 2016 with a population of 63,166, and was one of Canada's fastest growing cities between 2001 and 2006.

The city adopted the trumpeter swan as an official symbol due to its proximity to the migration route and summer nesting grounds of this bird. For that reason, Grande Prairie is sometimes nicknamed the "Swan City". The dinosaur has emerged as an unofficial symbol of the city due to paleontology discoveries in the areas north and west of Grande Prairie.
