SOLAR PROTON STORM IN PROGRESS: Energetic protons from the sun are raining down on Earth. They were accelerated in our direction by yesterday’s powerful X-class solar flare (described below). This is called a “solar proton storm,” and currently it is category S3. Shortwave radios inside the Arctic Circle aren’t working right now due to this storm, which is causing a polar cap absorption event. Currently, there is no danger to air travelers.
