Aurora vs Huamachuco

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.

Huamachuco (possibily from Quechua waman, falcon or variable hawk, and Kulyi chuco, earth or land, "land of falcons") is a town in northern Peru and capital of the province Sánchez Carrión in La Libertad Region. The city is the seat of the Territorial Prelature of Huamachuco. Lake Sausacocha lies to the northeast. About 30 miles away, within the Huamachuco district, is the significant archeological site of Marcahuamachuco.

It is a complex of monuments, a prehistoric political and religious center of a culture that thrived 350 CE-1100 CE. The ruins of a Wari city, Viracochapampa, are located 3.5 km north of Huamachuco. Additionally there are many other pre-Columbian ruins around the town.
