Biratnagar vs Aurora

Informations

Biratnagar (Nepali: विराटनगर) is a metropolitan city in Nepal, which serves as the capital city of Province No. 1. With a population of 242,548 as per the 2011 census, it is the largest city in the province and also serves as the headquarters of Morang district. Biratnagar is located 399 km (248 mi) east of the capital, Kathmandu and 6 km (3.7 mi) north of the bordering town of Jogbani in the Indian state of Bihar. The highest peak in the world, Mount Everest, is located 174 km (108 mi) north of the city. Biratnagar was declared a metropolitan city on 22 May 2017, thus pushing the total population to over 240,000 making it the fourth most populated metropolitan city in the country after the urban agglomeration of Kathmandu and Lalitpur, Pokhara, and Bharatpur.

The city is home to the Biratnagar Jute Mills, the first large scale industry of Nepal. It also serves as an entry point to eastern Nepal as well as north-eastern India. Biratnagar is the second Nepalese city, after Janakpur, to have a connection with the Indian Railways and the only city after Birgunj to operate an integrated check post (ICP) on the Indian border. Considered to be the industrial capital of Nepal, the city is also the birthplace of five prime ministers of Nepal, in addition to being host to a number of revolutionary incidents in the country including the first labor strike which led to the anti-Rana movements.

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.
