Solar Flare Causes "Ground Level Event"

GROUND 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.

The solar radiation storm was so strong, some of these particles reached the surface of Earth.
