Abstract text
Hundreds of amateur radio operators (hams) collaborated to monitor the impact of the April 2024 total solar eclipse on radio communications. By analyzing ham radio logs (ground-to-ground communication) along with PHaRLAP ray-trace modeling, we investigate how the eclipse altered high-frequency (HF) radio propagation and the Earth’s ionosphere. Our results demonstrate that the eclipse affected HF radio links variably across different frequency bands (3.5, 7, 14, and 21 MHz) and propagation paths across the Contiguous United States (CONUS) and over the Atlantic Ocean to Europe. By combining real-world observations with simulations, we validate ionospheric model predictions (such as SAMI3 and SAMI3/WACCM-X) for eclipse-driven changes. We will present the results obtained on how solar eclipses modulated the ionosphere and HF radio communications.
