Sucre vs Aurora

Informations

Sucre (Spanish: [ˈsukɾe]) is the constitutional capital of Bolivia, the capital of the Chuquisaca Department and the 6th most populated city in Bolivia. Located in the south-central part of the country, Sucre lies at an elevation of 2,810 meters (9,214 feet). This relatively high altitude gives the city a subtropical highland climate with cool temperates year-round.

Its pre-Columbian name was Chuquisaca; during the Spanish Empire it was called La Plata. Before the arrival of the Spanish, the city of Chuquisaca had its own autonomy with respect to the Inca Empire (the Charcas were the only people that did not pay the ransom for the Inca captive).

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.
