Aurorae (Northern Lights)
Beautiful ribbons of light caused by the interaction of high-energy particles in the solar wind and Earth's magnetic field.
Northern lights--an older name for the polar aurora.
Orbit--the line followed by a spacecraft or a celestial body. See Sun synchronous orbit, synchronous orbit.
NORTHERN LIGHTS
Northern lights is another name for auroras that appear in the Northern Hemisphere. Auroras are beautiful undulating sheets of light in the near-polar sky.
Northern lights is another name for auroras that appear in the Northern Hemisphere. Auroras are beautiful undulating sheets of light in the near-polar sky. They are caused by gases that become excited after being hit by solar particles.

While the northern lights (Aurora Borealis) are a common feature of the Arctic and far north, viewers in Britain must be looking at exactly the right time to be lucky enough to see them.
northern lights (NASA SP-7, 1965) = aurora borealis. northern sky (NASA Thesaurus) That part of the sky visible from the northern hemisphere.
Also called the northern lights (or southern lights in the southern hemisphere). The aurora is a shimmering curtain of green and/or red light seen toward the north (in the northern hemisphere).

In Scotland, the northern lights were known as "the merry dancers" or na fir-chlis''. There are many old sayings about them, including the Scottish Gaelic proverb "When the merry dancers play, they are like to slay.

Also called aurora polaris, northern lights . auroral zone A roughly circular band around either geomagnetic pole above which there is a maximum of auroral activity. It lies about 10 to 15° of geomagnetic latitude from the geomagentic poles.
northern daybreak; popularly called northern lights. A luminous meteoric phenomenon, visible only at night, and supposed to be of electrical origin.
One better-known effect of the magnetospheric substorm is called the aurora, also known as the northern lights. The aurora takes place when the solar wind collides with the Earth's ionosphere.
Auroral emissions, similar to Earth's northern lights, were observed in the polar regions of Jupiter. The auroral emissions appear to be related to material from Io that spirals along magnetic field lines to fall into Jupiter's atmosphere.
Also known as the northern lights, this is an atmospheric phenomenon that displays a diffuse glow in the sky in the northern hemisphere. It is caused by charged particles from the Sun as they interact with the Earth's magnetic field.
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.
Reaching Earth, these flares trigger the aurora borealis - the Northern Lights - which are those broad luminous display of lights seen floating high above Earth's Northern Hemisphere upper latitudes.
These particles can on occasion interact with the Earth's atmosphere and produce the aurora, or northern lights. During a large expulsion of particles (as you'll see below) the northern lights can become very spectacular.
Aurora are also known as the northern lights (aurora borealis) and the southern lights (aurora australis).
AURORA POLARIS (Aurora Borealis and Australis, Polar Light, Northern Lights), a natural phenomenon which occurs in many forms, some of great beauty.
Aurora emissions, similar to Earth's Northern Lights, have been observed at Jupiter's poles and appear to be related to material from Io that spirals along magnetic field lines eventually falling into Jupiter's atmosphere.
aurora borealis
The aurora in the Northern Hemisphere, also known as the Northern Lights.
Atmospheric event seen in the polar regions - colourful light displays occur when solar winds meet the edge of Earth's magnetic field. Known as: Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights)

Aurora Information and Forecasts
Here is a general discussion of auroras. The Aurora Page has information, links, and images about the northern lights, including links to current sighting reports and aurora forecasts.
Auroras have been seen on several planets in our solar system. On Earth, auroras are also known as the "Northern Lights" (aurora borealis) or "Southern Lights" (aurora australis), depending on in which polar region they appear.
Those that occur during magnetic storms can create extremely impressive spectacles. The Aurora australis, or "Southern Lights" occur near the South Pole while the Aurora borealis, or "Northern Lights" occur near the North Pole.
In the northern hemisphere, the aurorae are called aurora borealis or ``the northern lights'' and in the southern hemisphere, they are called aurora australis or ``the southern lights.
(Sec. 4.2) Aurorae are most brilliant at high latitudes, especially inside the Arctic and Antarctic circles. In the north, the spectacle is called the aurora borealis, or Northern Lights.
Bootes is at the top of the picture, Serpens Caput at the lower right, Hercules at lower left. The faint vertical red and green bands in the background are from a weak northern lights display. North is toward the upper left.
When the interplanetary field switches to a direction opposite the Earth's field, or when big clouds of particles enter it, the fields in the magnetotail reconnect and energy is released, producing the aurora borealis (northern lights).
