AURORA BOREALIS DAY

http://www.geo.mtu.edu/weather/aurora/
The first display of the northern lights was recorded in America. The sighting was made in New England on this day in 1719. The report said that a mysterious face seemed to appear in the atmosphere; and, since most aurora borealis displays occur in September and October and again in March and April, this is very strange, indeed!

The simplest explanation for the green, red, and frost-white northern lights is that, just as the gas in a neon light glows when charged with electricity, so the gas in the atmosphere glows with specific colors when charged with electric particles from the sun. For a more technical explantation, see Mankind’s Explanation: Aurora Borealis or Aurora Season Begins.

As far as we know, there is still no technical explanation for the off-season display.
