On Thursday, April 11, the sun let off an M6.5 solar flare and its accompanying coronal mass ejection, more commonly called a CME, which is directed at Earth. The solar particles that result from such an event are traveling at a speed of about 600 miles per second, and are expected to reach Earth Friday night into the weekend. Such an event disrupted some radio communications.
Before you begin imaging a scenario similar to certain end-of-times movies where characters go from innocently watching television to being shrouded in darkness and chaos, keep in mind this event will be far less eventful, possibly disrupting radios and GPS starting Friday night. Because the event was observed, some preparations can be made in anticipation of the incoming solar particles, helping protect satellites and other vulnerable equipment from damage.
