Re: [meteorite-list] Aurora Borealis last night (was: Geminid MeteorShower Count)

Thanks for posting that, Bernd.
That explains a sighting I experienced in southern Illinois around that 
date.
I stepped outside for some fresh air after a late night band rehearsal and 
for a moment thought that the sunset was still lingering. Then I realized it 
was well after midnight. There were large, shifting areas of pink and 
purplish colors, rather than the green which is apparently more common. That 
was the only time I've ever seen the aurora, but I'd sure like to get up to 
Alaska and take in some more. I still haven't seen a total solar eclipse 
either. One of these days...

Hello mt and List,

Sky  Telescope, July 1981, p. 86: April's Intense Auroral Display

On April 10th, at about 16:55 Universal time, the Sun spewed a solar flare
from a region near the center of' its disk. It was a modest flare by solar
standards, but the high-energy electrons and protons it sent speeding out
into the planetary system were on a collision course with Earth.

Their arrival some 58 hours later was nothing short of spectacular, 
producing

an aurora reported = as far south as the Mexican border and Florida. =

The associated geomagnetic storm was more intense than any since those
resulting from the great solar Flares of August, 1972.

Best pre-Xmas wishes,

Bernd

Good morning Listees and Listoids,

Last night Linton also wrote:

Sky  Telescope, July 1981, p. 86:

Auroras above 240 km (150 miles) are mainly red from light
given off by oxygen atoms. Between 100 and 240 km it is the
green light from oxygen that is most apparent, and below these
altitudes the red and blue light of nitrogen atoms is strongest.
It is likely this latter source was responsible for much of the
April [1981] display.

Cheers,

Bernd
