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.

Informations

Alajuela (Spanish pronunciation: [alaˈxwela]) is a district in the Alajuela canton of the Alajuela Province of Costa Rica, known as “The Capital of the World” by the locals. As the seat of the Municipality of Alajuela canton, it is awarded the status of city. In virtue of being the city of the first canton of the province, it is also the capital of the Province of Alajuela.



Because of its location in the Costa Rican Central Valley, Alajuela is nowadays part of the conurbation of the Greater Metropolitan Area. The city is the birthplace of Juan Santamaría, the national hero of Costa Rica and the figure who gives the name to the country's main international airport, which is south of Alajuela downtown.
