Summary
On June 30, sunspot region AR4479 unleashed an X1.1-class solar flare that peaked at 4:50 p.m. EDT, triggering strong (R3) radio blackouts across parts of North America. The X-rays reached Earth in just over 8 minutes, causing temporary signal degradation for high-frequency radio users. A coronal mass ejection accompanied the flare.
