Solar flare causes 'Ground Level 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.
