Sun's 19-Day Radio Burst Sets New Solar Record
TL;DR
NASA scientists tracked a Type IV solar radio burst that lasted 19 days in August 2025—the longest on record—originating from a helmet streamer in the Sun’s atmosphere. The event may have been sustained by three coronal mass ejections and was observed by a fleet of missions (STEREO, Parker Solar Probe, Wind, Solar Orbiter) across the inner solar system, enabling a detailed timeline. Understanding these long-lasting bursts could improve space weather forecasts and protect satellites and spacecraft.
