X-class solar flare could cause 'radio blackout' for GPS, communications

The sun emitted a X1 solar flare on Saturday which NASA believes could hurt communications systems on Earth on Wednesday.

According to the National Weather Service's Space Weather Prediction Center, the X1 solar flare could affect satellites and cause GPS errors, PC World reported.

They also said that electrical power lines may be hit by extra current, and high frequency communications could be blocked when the radiation hits Earth.

Extreme ultraviolet light streams out of an X-class solar flare as seen in this image captured on March 29, 2014, by NASA's Solar Dynamics Observatory. This image blends two wavelengths of light: 304 and 171 Angstroms, which help scientists observe the lower levels of the sun's atmosphere.

This flare is classified as an X.1-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
