Aurora vs Matsue

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.

Informations

Matsue (Japanese: 松江市, Hepburn: Matsue-shi) is the capital city of Shimane Prefecture, Japan, located in the Chūgoku region of Honshu.Matsue has an estimated population of 205,402 (2017) following the merger with Higashiizumo from Yatsuka District. Matsue is located at the northernmost point of Shimane Prefecture, between Lake Shinji and Nakaumi on the banks of the Ohashi River connecting the two lakes, though the city proper reaches the Sea of Japan coast.

Matsue is the center of the Lake Shinji-Nakaumi metropolitan area, and with a population of approximately 600,000 is the second largest on the Sea of Japan coast after Niigata. Matsue is sometimes called the "water city" (水の都) due to the prominence of the lakes, rivers and canals in the city-scape and scenery.Matsue is home to the Tokugawa-era Matsue Castle, one of the last surviving feudal castles in Japan.
