Sun unleashes huge solar flare
The bright source of the flare can be seen close to the centre of the Sun

The Sun has unleashed its strongest flare in four years, observers say.
The eruption is a so-called X-flare, the strongest type; such flares can affect communications on Earth.
Nasa's Solar Dynamics Observatory (SDO) spacecraft recorded an intense flash of extreme ultraviolet radiation emanating from a sunspot.
The British Geological Survey (BGS) has issued a geomagnetic storm warning, and says observers might be able to see aurorae from the northern UK.
The monster flare was recorded at 0156 GMT on 15 February and directed at the Earth.
Preliminary data from the Stereo-B and Soho spacecraft suggest that the explosion produced a fast but not particularly bright coronal mass ejection (CME) - a burst of charged particles released into space.
The unpredictable eruptions on the Sun can interfere with modern technology on Earth, such as electrical power grids, communications systems and satellites.
