Active Region 12339
Coronal Mass Ejection From 05 May To Miss Earth
published: Monday, May 11, 2015 14:10 UTC

The coronal mass ejection associated with the R3 (Strong) radio blackout observed shortly after 2200 UTC (1800 EDT) on 05 May 2015 is expected to miss Earth.

R1-R2 (Minor-Moderate) radio blackouts are likely over the next few days due to the flare potential of Active Regions 12335 and 12339.
