Solar Flares
Source GM Core pg. 96
Sometimes a star releases bursts of intense energy that are visible as flares of roiling plasma arcing out from its surface. Creatures and objects on or near a star's surface take massive fire damage and major persistent electrical damage from a solar flare. Solar flares disrupt technology up to millions of miles away from the star. A solar flare causes electronics and radio communications to gain the glitching condition or stop working for up to 1d6 hours.
