Solar weather events—such as solar flares, coronal mass ejections, and geomagnetic storms—significantly influence HF radio propagation by altering Earth’s ionosphere, often affecting signal reach and reliability for amateur radio operators. Recent activity allowed the northern lights to become visible as far south as Illinois, coinciding with solar storms that impacted radio and GPS communications. This presentation explores the science behind these phenomena, their direct effects on HF bands, and practical tips for hams to interpret solar indices and adapt to changing conditions.
We look forward to seeing you on Zoom!
