	NOAA Home Page - Question of the Month
		The aurora borealis and aurora australis (Latin for "northern" and "southern" dawn, respectively) occur in symmetric ovals centered on the northern and southern magnetic poles of Earth.
		The aurora is formed when charged particles (electrons and protons) are guided by the Earth's magnetic field into the atmosphere near the poles.
		The aurora is a near daily occurrence somewhere on Earth and there is almost always an aurora in the sky (both day and night, but in the daytime it is out-shined by sunlight).

	Aurora (phenomenon) - MSN Encarta
		It is named specifically, according to its location, aurora borealis (northern lights) or aurora australis (southern lights).
		The aurora consists of rapidly shifting patches and dancing columns of light of various hues.
		The period of maximum and minimum intensity of normal auroras seems to be almost exactly opposite that of the sunspot cycle, which is an 11-year cycle (see Sun), so the intensity of the auroras is normally low while the sun is very active.

	* Aurora borealis - (Astronomy): Definition
		Aurora Borealis - Light emitted by atoms and ions in the upper atmosphere near the north magnetic pole.
		The aurora borealis is seen in the north of the Northern hemisphere; the aurora australis in the south of the Southern.
		aurora borealis The Northern Lights caused by the interaction between the solar wind, the Earth's magnetic field and the upper atmosphere; a similar effect happens in the southern hemisphere where it is known as the aurora australis.

		This is one of the night sky's most regal displays-the aurora borealis, or "northern lights." Many times the aurora appears in a ring shape, circling around the dark sky like a splendid crown.
		The aurora borealis and aurora australis are mirror images of one another.
		The period of maximum and minimum intensity of the aurora follows almost exactly that of the sunspot cycle, which is an 11-year cycle.

	The Aurora Borealis and the Telegraph, a true, historical and eerie article
		The aurora is caused by rays or electrically charged particles shot from the sun, which are diverted toward the earth's atmosphere and change their electric charge.
		When the aurora is emitting a positive wave, the current on the line increases, and it neutralizes a battery totally when a negative wave is emitted.
		During the appearance of the aurora borealis on November 17, 1848, the soft iron armatures employed in the electric telegraph between Florence and Pisa remained attached to their electro-magnets, as if the latter were powerfully magnetized, without, however, the apparatus being in action and without the currents in the battery being set in action.

	Home of the Northern Lights
		My favorite time to view the aurora is in late August when a soft twilight is still visible all night, the temperatures are pleasant, and the bugs are minimal (however, cloud cover could be a major problem).
		As the aurora observing season comes to an end over high latitudes, capturing the aurora in twilight is common.
		Aurora activity was mild between the 3rd and 5th of March, 2001 but I managed to capture a couple of colorful images using Fuji Superia 800 @ f/2.0 between 5 and 15 secs.

		For example, the presentation gives a guide to the possibility that the aurora is located near a given location in the northern hemisphere under the conditions that existed at the time of the most recent polar satellite pass.
		The process to estimate the hemispheric power, and the level of auroral activity, involves using this normalization factor which takes into account how effective the satellite was in sampling the aurora during its transit over the polar region.
		A large (> 2.0) normalization factor indicates that the transit through the aurora was not very effective and the resulting estimate of auroral activity has a lower confidence.

	Aurora Borealis - Northern Lights
		As the solar wind interacts with the edge of the earth's magnetic field, some of the particles are trapped by it and they follow the lines of magnetic force down into the ionosphere, the section of the earth's atmosphere that extends from about 60 to 600 kilometres above the earth's surface.
		By studying the auroras, scientists can learn more about the solar wind, how it affects the earth's atmosphere and how the energy of the auroras might be exploited for useful purposes.
		he aurorae appear over the Earth’s polar regions in what are known as the auroral ovals; in the northern hemisphere the auroral oval bulges that much further to the south, the stronger the solar wind is at any given moment.

		The aurora borealis (the Northern Lights) and the aurora australis (the Southern Lights) have always fascinated mankind, and people even travel thousands of miles just to see the brilliant light shows in the earth's atmosphere.
		The auroras, both surrounding the north magnetic pole (aurora borealis) and south magnetic pole (aurora australis) occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere.
		The auroras generally occur along the "auroral ovals," which center on the magnetic poles (not the geographic poles) and roughly correspond with the Arctic and Antarctic circles.
