NOAA reported a significant X-ray event, or solar flare, that exceeded the M5 class on June 30, 2026, reaching a peak of M5.8. This moderate R2-level event caused limited blackouts of high-frequency (HF) radio communication.
The solar flare began at 12:37 UTC, peaked at 12:57 UTC, and concluded on July 1 at 13:23 UTC. Its origin was located at S07W55 on the sun.
The primary area of impact for this event was centered on the sub-solar point on Earth's sunlit side, leading to tens of minutes of disrupted HF radio signals.
