Aurora vs Blumenau

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.

Blumenau is a city in Vale do Itajaí, state of Santa Catarina, in the South Region of Brazil. It is 130 km (81 mi) away from the state capital of Florianópolis. The city was founded by the German chemist and pharmacist Hermann Bruno Otto Blumenau, who arrived on a boat via Itajaí-Açu River accompanied by seventeen other Germans.

It has a cultural agenda focused on parties based on the daily life and habits of European immigrants, with emphasis on German heritage, including the second largest Oktoberfest in the world, which takes place during 17 days in October.
