[meteorite-list] Aurora Borealis last night (was: Geminid Meteor Shower Count)

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,
