Solar flares can produce x-rays resulting in radio blackouts that block high-frequency radio waves. Solar Energetic Particles can penetrate satellite electronics and cause electrical failure. Coronal mass ejections (CMEs) can cause geomagnetic storms that induce ground currents and degrade power grid operations, sometimes catastrophically. The Sun, The Earth, and Near-Earth ...GOES-16/JPSS Case Exercise: Monitoring the Rhea Oklahoma Grassland Fire
