June 7, 2011 - A dramatic eruption from an otherwise unimpressive NOAA Region 1226 earlier today is expected to cause G1 (minor) to G2 (moderate) levels of Geomagnetic Storm activity tomorrow, June 8, beginning around 1800 UTC with the passage of a fast CME. A prompt Solar Radiation Storm reached the S1 (minor) level soon after the impulsive R1 (minor) Radio Blackout at 0641 UTC. The Solar Radiation Storm includes a significant contribution of high energy (>100 MeV) protons, the first such occurrence of an event of that type since December 2006.
