The strongest solar flare in four years disrupted radio communications in southern China, according to the China Meteorological Administration.
The solar flare, a huge explosion on the sun’s surface caused by magnetic activity, affected transmissions in southern China on Tuesday, Xinhua news agency reported, quoting the CMA.
The US space administration NASA confirmed that Monday’s solar flare was the largest in four years, and the event sparked predictions of heightened activity on the northern hemisphere of the sun.
“X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms,” disrupting telecommunications and electric grids, NASA said.
