2012-03-07 04:24 CMEs: One Arrives, Another Likely Tomorrow
The CME that erupted late on March 4 passed ACE around 0400 UTC March 7 (11:00 p.m. EST March 6). Look for G1 (minor) Geomagnetic Storm activity in the next few hours. Another CME, part of the recent R3 (strong) Radio Blackout event at 0024 UTC March 7 (7:24 p.m. EST March 6) is forecast to pass ACE about one day hence. Predictions are still being refined on this one. Finally a Solar Radiation Storm is now building as the higher energies are showing a response to the recent eruption. The S1 (minor) threshold should be surpassed in the next few hours. Updates here as conditions warrant.
