A severe solar radiation storm began today, 8 November, at 4:50 p.m. MST

Scales. The storm, which currently ranks as the fourth largest since
1976, is expected to peak over the course of the next several hours and
then slowly diminish over the next three to four days.

This severe radiation storm could pose a hazard to the astronauts on the
International Space Station as well as passengers on commercial
airlines flying at high latitudes. The storm could also adversely
effect the operation of satellites.
