Did you know? Here’s a space weather and radio propagation educational tidbit – from http://SunSpotWatch.com – at 14:00 UTC on 2017-06-29:

During a geomagnetic storm, there will be aurora in the northern and southern polar regions of the Earth. A Polar Cap Absorption (PCA) event is the result of intense ionization produced by energetic protons. A Polar Cap Absorption (PCA) event occurs over the polar regions (North and South Poles), and are produced by energetic protons which originate from class of large solar flares known as proton flares.

Proton flares (very strong flares) successfully accelerate protons to a good fraction of the speed of light. Energetic protons from proton flares reach Earth only minutes to hours later. Energetic protons reach Earth, spiral around, down magnetic field lines of Earth, penetrate into atmosphere.
