Space Weather Solar Radiation Storm Scale
Bursts of hard radiation from the sun affect high-altitude workers like airline pilots and astronauts. They also can kill or disable satellites and affect radio communications at high latitudes.

Space Weather Geomagnetic Storm Scale
When solar wind bursts push the Earth's magnetosphere around, the geomagnetic havoc can shake up electric power grids, damage spacecraft, send dangerous electric surges down pipelines, and wipe out radio navigation signals.
