LEVEL RADIATION EVENT: Sunday's powerful X8-class solar flare from
departing sunspot AR2673 accelerated a swarm of protons toward Earth,
producing a strong solar radiation storm and a "ground level event"
(GLE). High-energy particles normally held at bay by Earth's atmosphere
and magnetic field penetrated all the way to the ground on Sept. 10th.
A leading analyst of GLEs says that radiation dose rates onboard
commercial jets flying at high latitudes may have briefly doubled
during the episode.

Above: The 'snow' in this Sept. 10th image from a coronagraph onboard
the orbiting Solar and Heliospheric Observatory (SOHO) is caused by a
blizzard of energetic particles striking the spacecraft's digital
camera. The solar radiation storm was so strong, some of these
particles reached the surface of Earth.
