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).

York is a cathedral city and unitary authority area at the confluence of the rivers Ouse and Foss in England. The city is the county town of the historic county of Yorkshire. York is the most populous district within the lieutenancy area of North Yorkshire and second largest built-up area. City of York Council is a unitary authority responsible for providing all local services and facilities throughout the city and rural areas beyond the old city boundaries. The unitary authority is in the Leeds city region along with most of the former West Riding of Yorkshire, apart from South Yorkshire (in the Sheffield city region) and Derbyshire. At the 2011 census, the borough population was 198,051 and the population of the city was 153,717.
The city is known for its famous historical landmarks such as York Minster and the city walls, as well as a variety of cultural and sporting activities, which makes it a popular tourist destination in England. It is about 25 miles (40 km) north-east of Leeds and 34 miles (55 km) north-west of Kingston upon Hull.
The city was founded by the Romans as Eboracum in 71 AD. It became the capital of the Roman province of Britannia Inferior, and later of the kingdoms of Deira, Northumbria and Jórvík.
