Spaceweather.
THE BIG STORM IS OVER: NOAA forecasters say that the storm is really over now. There's no chance of additional G5 activity this week because all the big CMEs have already come and gone. However, relatively minor G1 or G2-class storms are possible on May 13th in response to a glancing blow from an off target CME.
The danger could return on May 15th however. On that date the sunspot will pass through a region of the sun magnetically connected to Earth via the Parker sprial. Subatomic debris (protons and electrons) from explosions on May 15th and 16th could spiral back to Earth and rain down our planet. This is called a "radiation storm;" it can upset satellite electronics and cause polar radio blackouts.
