Pitești vs Aurora

Informations

Pitești (Romanian pronunciation: [piˈteʃtʲ], German: Piteschti) is a city in Romania, located on the Argeș River. The capital and largest city of Argeș County, it is an important commercial and industrial center, as well as the home of two universities. Pitești is situated in the historical region of Muntenia. It lies on the A1 freeway connecting the city directly to the national capital Bucharest, being an important railway junction, with a classification yard in nearby Bălilești. The city houses the Arpechim oil refinery, and is a marketing center for the automotive industry, in particular Automobile Dacia.

Inhabited since prehistoric times but first mentioned in the 14th century, it developed as a trading town in northern Wallachia, serving as an informal residence for various Wallachian Princes until the 18th century. From the 19th century and until the interwar period, it was an important political center for the National Liberal Party and the main residence of the Brătianu family of politicians. During the early stages of the communist regime, it was one of the main sites of political repression, with the Pitești prison becoming home to an experiment in brainwashing techniques.

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.
