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).

Barrie is a city and manifesting regional centre in Central Ontario, Canada, located on the shores of Kempenfelt Bay, the western arm of Lake Simcoe. The city is located geographically within Simcoe County, however it is a politically independent single-tier municipality. It is within the historically significant Huronia region of Central Ontario, and is part of the Greater Golden Horseshoe, a densely populated and industrialised sub-region of Ontario. As of the 2016 census, the city's population was 141,434 making it the 34th largest in Canada in terms of population proper. The Barrie census metropolitan area (CMA) as of the same census had a population of 197,059 residents, making it the 21st largest CMA in Canada. The city itself has seen significant growth in recent decades due to its emergence as a bedroom community for Toronto. The affordability of housing and robust job market perhaps contribute to a Toronto buyer's appeasement with Barrie. GO Transit offers daily service to and from the Greater Toronto Area from two stations in the city. Barrie is located 85 kilometres (53 mi) north of Toronto, 355 kilometres (221 mi) northeast of Detroit and 335 kilometres (208 mi) west of Ottawa. This represents the city's highly centralised and historically advantageous situation, providing an ease of access to major centres and airports across the region.The Barrie area was first settled during the War of 1812 as a key supply depot for British forces.
