The sun emitted a significant solar flare, peaking at 7:42 a.m. EDT on June 10,
2014. NASA's Solar Dynamics Observatory – which typically observes the entire
sun 24 hours a day -- captured images of the flare.
Solar flares are powerful bursts of radiation. Harmful radiation from a flare
cannot pass through Earth's atmosphere to physically affect humans on the
ground. However, when intense enough, they can disturb the atmosphere in the
layer where GPS and communications signals travel.
To see how this event may affect Earth, please visit NOAA's Space Weather
Prediction Center at http://spaceweather.gov, the U.S.
government's official source for space weather forecasts, alerts, watches and
warnings.
This flare is classified as an X2.2 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.
Updates will be provided as needed.
