Washington, D.C. – A powerful solar flare is already disrupting high-frequency radio communications this morning, with impacts possible across aviation, marine operations, and emergency communications through at least late morning Friday.
According to the NOAA Space Weather Prediction Center, an X2.5-class solar flare peaked at 4:13 a.m. EDT, triggering an R3-level (strong) radio blackout on the sunlit side of Earth. These events can cause immediate signal degradation or complete loss of HF radio communication for minutes to several hours.
The greatest impacts are expected across North America, particularly affecting transoceanic flights, maritime traffic, and any systems relying on high-frequency radio bands. Pilots and ship operators may experience intermittent communication outages, while GPS accuracy could briefly degrade in some regions.
Emergency managers and operators relying on radio systems should be prepared for brief disruptions and use backup communication methods if available. Most consumer devices will not be directly affected, though some users may notice minor navigation or signal inconsistencies.
Conditions are expected to gradually improve by late morning to early afternoon as the flare’s effects diminish. Additional solar activity remains possible, and further alerts could be issued if new eruptions occur.
