Cavalese vs Aurora

Informations

Cavalese (German: Gaßlöss) is a comune of 4,004 inhabitants in Trentino, northern Italy, a ski resort and the main center in the Fiemme Valley. It is part of the Magnifica Comunità di Fiemme (Magnificent Community of Fiemme) and, together with Predazzo, is the administrative, cultural and historical center of the valley. The town is a renowned tourist location, during winter for cross-country and alpine sky, and during summer for excursions.

The town was the site of the Cavalese cable car disaster in 1998, when a US aircraft tore down the cable-car connecting the town to the nearby Cermis mountain during a training exercise, killing 20 people.

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.
