Huge solar flare jams radio communications
The sun has unleashed its strongest flare in four years, Nasa said, as astronomers in southern China reported disturbances to radio communications.
The massive Class X flash - the largest such category - erupted at 0156 GMT Tuesday, according to the US space agency.
"X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms," disturbing telecommunications and electric grids, Nasa added. The China Meteorological Administration reported a large solar flare and electromagnetic storms jammed shortwave radio communications in southern China, according to the official Xinhua news agency.
