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 Received on Tue 14 Dec 2010 02:18:21 PM PST |
