Moderate Solar Flare Triggers Brief Radio Blackouts

A moderate R2-class solar flare, classified as an M5.5 X-ray event, occurred on July 5, 2026, potentially causing limited high-frequency (HF) radio communication blackouts.

The event began at 1751 UTC, reached its peak intensity at 1757 UTC, and concluded by 1802 UTC. Its origin was located at N15W87 on the sun.

The primary impact area is centered on the sub-solar point on Earth's sunlit side, where HF radio blackouts could last for tens of minutes.
