Comodoro Rivadavia vs Aurora

Informations

Comodoro Rivadavia (Spanish pronunciation: [komoˈðoɾo riβaˈðaβja]) is a city in the Patagonian province of Chubut in southern Argentina, located on the San Jorge Gulf, an inlet of the Atlantic Ocean, at the foot of the Chenque Hill. Comodoro Rivadavia is the most important city of the San Jorge Basin, and the largest city south of the southern 45th parallel. The city is often referred to simply as Comodoro. It was at one time the capital of the Comodoro Rivadavia Territory, which existed from 1943 to 1955. The territory was a part of Chubut before and after its creation, and the city became the capital of the Escalante Department. It had a population of 137,061 at the 2001 census [INDEC], and grew to 182,631 by the 2010 census.Comodoro Rivadavia is a commercial and transportation center for the surrounding region, the largest city of Chubut, and an important export point for a leading Argentine petroleum district. A 1,770 km pipeline conveys natural gas from Comodoro Rivadavia to Buenos Aires. Founded by decree on February 23, 1901, as a port for the inland settlement of Sarmiento, the first settler was Francisco Pietrobelli. Early settlers included Boers escaping British rule in South Africa, as well as Welsh settlers.

The town was named in honour of shipping minister Martín Rivadavia, a proponent of the development of Southern Argentina. It has been prosperous since 1907, when a drilling crew searching for water struck oil at a depth of 539 m. The city is the home of the main faculty of the National University of Patagonia San Juan Bosco. The Cathedral is the seat of the Diocese of Comodoro Rivadavia, of which the Bishop is, since 2005, Virginio Domingo Bressanelli. The Cathedral is dedicated to San Juan Bosco, the only cathedral in the world dedicated to the founder of the Salesian Order. It was inaugurated in 1979, although the crypt itself had been dedicated in 1949. Rada Tilly is a beach resort and now suburb 12 km south of Comodoro. The National Museum of Petroleum is located in the General Mosconi neighbourhood 3 km north of central Comodoro Rivadavia. It was opened in 1987 by the state-owned oil company YPF. Comodoro Rivadavia is served by General Enrique Mosconi International Airport (Airport Code CRD/SAVC) with daily flights to Buenos Aires and many other Patagonian cities, as it is the main hub of LADE.

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.
