and we were discussing abt it yst night

guess y i suddenly talk abt it ne way

CUZ I WENT TO SEE xx blog

den i saw the aurora-northern lights

An aurora (plural aurorae/auroras) is an electro-static phenomenon, characterised by a bright glow and caused by the collision of charged particles in the magnetosphere with atoms in the Earth's upper atmosphere.
Auroras are usually observed in the night sky, particularly in the polar zone

Auroras are now known to be caused by the collision of charged particles (ions (+) (-) ) found in the magnetosphere, with atoms in the Earth's upper atmosphere (at altitudes above 80 km). These charged particles are typically energized to levels between 1 and 15 keV and, as they collide with atoms of gases in the atmosphere, the atoms become excited. Shortly afterwards, the atoms emit their gained energy as light (see Fluorescence). Light emitted by the Aurora tends to be dominated by emissions from atomic oxygen, resulting in a greenish glow (at a wavelength of 557.7 nm) and - especially at lower energy levels and at higher altitudes - the dark-red glow (at 630.0 nm of wavelength). Both of these represent forbidden transitions of electrons of atomic oxygen that, in absence of newer collisions, persist for a long time and account for the slow brightening and fading (0.5-1 s) of auroral rays. Many other colors - especially those emitted by atomic and molecular nitrogen (blue and purple, respectively)[1] - can also be observed. These, however, vary much faster and reveal the true dynamic nature of auroras.
