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).

Varna (Bulgarian: Варна, pronounced [ˈvarnɐ]) is the third-largest city in Bulgaria and the largest city and seaside resort on the Bulgarian Black Sea Coast. Situated strategically in the Gulf of Varna, the city has been a major economic, social and cultural centre for almost three millennia. Historically known as Odessos (Ancient Greek: Ὀδησσός), Varna developed from a Thracian seaside settlement to a major seaport on the Black Sea.
