“17.3.2013. 500th deviation, woot! And one of my best shots from sunday night :D EDIT: Took another shot at the postprocessing, the first one was shoddy. I think I’ll have to go through the other pics I’ve uploaded and do the same.”

Picture of the Aurora Borealis or, more commonly known as the Northern Lights.


“An aurora (plural: aurorae or auroras; from the Latin word aurora, “sunrise” or the Roman goddess of dawn) is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in themagnetosphere and solar wind and, on Earth, are directed by the Earth’s magnetic field into the atmosphere. Most aurorae occur in a band known as the auroral zone,[1][2] which is typically 3° to 6° in latitudinal extent and at all local times or longitudes. The auroral zone is typically 10° to 20° from the magnetic pole defined by the axis of the Earth’s magnetic dipole. During a geomagnetic storm, the auroral zone expands to lower latitudes.

Aurorae are classified as diffuse or discrete. The diffuse aurora is a featureless glow in the sky that may not be visible to the naked eye, even on a dark night. It defines the extent of the auroral zone. The discrete aurorae are sharply defined features within the diffuse aurora that vary in brightness from just barely visible to the naked eye, to bright enough to read a newspaper by at night. Discrete aurorae are usually seen in only the night sky, because they are not as bright as the sunlit sky. Aurorae occasionally occur poleward of the auroral zone as diffuse patches[3] or arcs (polar cap arcs[4]), which are generally invisible to the naked eye.

In northern latitudes, the effect is known as the aurora borealis (or the northern lights), named after the Romangoddess of dawn, Aurora, and the Greek name for the north wind, Boreas, by Pierre Gassendi in 1621.[5] Auroras seen near the magnetic pole may be high overhead, but from farther away, they illuminate the northern horizon as a greenish glow or sometimes a faint red, as if the Sun were rising from an unusual direction. Discrete aurorae often displaymagnetic field lines or curtain-like structures, and can change within seconds or glow unchanging for hours, most often in fluorescent green. The aurora borealis most often occurs near the equinoctes. The northern lights have had a number of names throughout history. The Cree call this phenomenon the “Dance of the Spirits“. In Medieval Europe, the auroras were commonly believed to be a sign from God.[6] ~taken form Wikipedia

Its southern counterpart, the aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone.[7] It is visible from high southern latitudes in AntarcticaSouth AmericaNew Zealand, and Australia. Aurorae occur on other planets. Similar to the Earth’s aurora, they are visible close to the planet’s magnetic poles. Modern style guides recommend that the names of meteorological phenomena, such as aurora borealis, be uncapitalized.[8]
