Extreme ultraviolet radiation from the flare ionized the top of Earth's atmosphere, causing a deep shortwave radio blackout over the Americas. Ham radio operators, aviators and mariners may have noticed a sudden loss of signal at all frequencies below 30 MHz.
Subatomic debris from this event might soon reach Earth, guided toward our planet by the Parker Spiral. Also, a CME might be in the offing. Stay tuned for updates!
