Scientists used sound waves in the sun to predict the active regions' arrival.
"It's like getting an early warning of possible freezing temperatures in spring — the weather forecast may have some large uncertainties, but one could start preparing to take mitigating actions to save their flowering orchard from freezing."
GONG relies on a technique called helioseismic holography, which uses soundwaves bouncing through the interior of the sun to develop a picture of solar activity on the side of our star facing away from us. , but none directed toward Earth so far. CMEs are explosive outbursts of plasma and charged particles capable of carrying billions of tons of material from the sun at speeds of hundreds of miles per hour.
CMEs can be harmful to astronauts and space technology, and if these strongly magnetic plasma bursts lash Earth's protective magnetic bubble, the magnetosphere, they can create a disturbance that sends particle radiation into the upper layers of
