Aurora vs Limeira

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.

Limeira is a city in the eastern part of the Brazilian state of São Paulo. The population is 300,911 (2017 est.) in an area of 581 km². The elevation is 588 m. It is 154 km from São Paulo, the state capital, and 1011 km from Brasilia, Brazil's capital. The city can be easily reached from São Paulo by two highways: Rodovia Anhanguera and Rodovia dos Bandeirantes. Once an important and strategical pole of the coffee culture, Limeira was also known as the "Brazilian orange capital" due to the great citrus production that occurred in the past, although now the main crop cultivated in the city is the sugar cane. Afterwards, it became recognized by its new plated jewelry and semi-jewelry industry which attract customers from all over the world, giving the city the title of "Brazil's plated jewelry capital". There are more than 450 companies that are responsible for half of Brazil's exports in this sector. There is a famous farm located in Limeira, Fazenda Ibicaba, that belonged to Nicolau de Campos Vergueiro, who brought the first immigrants from Europe, especially from Germany, Portugal, Switzerland and Belgium, to replace the enslaved African-Brazilian workers, which was basically a government effort to "bleach" the race, as it was feared Brazil would become a "black country".

Limeira is thus said to have accomplished the first positive experience with immigrant workers in Brazil. Probably because Northern Europeans preferred to run their own farms rather than to subject themselves to indentured work and the Portuguese tended to work in commerce, Italian immigrants were brought to work the fields. Such immigrant groups were greater in numbers than all the others all over São Paulo state. Northern Europeans and the first Italians to arrive in the country often came with the promise of being granted lands in exchange for their work, but the last ones were treated socially only better than the slaves themselves. The latter, nonetheless, had nowhere to go for jobs as slavery ended and many begged to be rehired for food. The situation of some of them improved when the British installed the railway in the country and gave them prestigious jobs with housing. Today, Limeira is located in a prosperous region in São Paulo State. A.A. Internacional is a traditional football club based in Limeira, along with Independente F.C. The city's biggest stadium is the Major José Levy Sobrinho stadium, built in 1977. The city's basketball team is Associação Limeirense de Basquete, which plays in the Novo Basquete Brasil and the Liga Sudamericana. Its home arena is the Ginásio "Vô" Lucato.
