Radio not working? Internet on the blink? It could be because radiation from the largest solar flare in four years has reached earth. Solar flares are intense, short-lived bursts of energy, and can cause interference with communication devices.
REUTERS - Radiation from the largest solar flare in four years is expected to reach Earth late on Thursday or Friday.
Such events can cause radio blackouts and interfere with communication satellites, but the most likely outcome this time will be brilliant Northern Lights displays, U.S. scientists said.
NASA scientists on Monday reported an X-class solar flare, the first in more than four years. X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms.
It was one of a series of three solar flares and prompted speculation that a new solar cycle may be ramping up.
