A solar flare has erupted from the sun in an impressive display captured by NASA cameras.
NASA says the flare peaked on Tuesday and created a large cloud that appeared to cover almost half the surface of the sun.
Images were recorded by an orbiting satellite called the Solar Dynamics Observatory.
Solar energy released by the event should deliver a "glancing blow" to Earth's magnetic field on Wednesday or Thursday, NASA said.
But it's not expected to cause a major impact.
The US National Weather Service is predicting minor effects on satellites and weak impacts on some power grids.
