Title: Aurora Borealis
Post by: muman613 on January 29, 2012, 12:47:12 AM
The earth has been experiencing an increase in solar activity for the last week or two. Originally there was concern that it may cause problems for the power grid but now it seems that the only observable effect of the increased solar activity is an increase in the aurora borealis.

An aurora (plural: auroras or aurorae) 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 the magnetosphere and solar wind and, on Earth, are directed by the Earth's magnetic field into the atmosphere. Aurora is classified as diffuse or discrete aurora. 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 will expand to lower latitudes. The diffuse aurora is a featureless glow in the sky which may not be visible to the naked eye even on a dark night and defines the extent of the auroral zone. The discrete aurora are sharply defined features within the diffuse aurora which vary in brightness from just barely visible to the naked eye to bright enough to read a newspaper at night. Discrete aurorae are usually observed only in the night sky because they are not as bright as the sunlit sky. Aurorae occur occasionally poleward of the auroral zone as diffuse patches[3] or arcs (polar cap arcs[4]) which are generally invisible to the naked eye.

The awesome beauty of nature is a revelation of Hashem in this world. The creation testifies to the existence of the creator.

Here is the cause for the increased activity...

Wish I could see the Aurora Borealis from where I live.

You mean the pole shift.

That's really beautiful. Maybe one day I'll travel to a place I can see it.

You mean the rapid earth crust movement.

I used to live in the North, but I don't remember if I saw it.

I believe it is called Northern Lighting
