Sun Erupts With Significant Solar Flare | NASA SDO

NASA's Solar Dynamics Observatory captured images of a solar flare—as seen in the bright flash on the right side—on Sept. 10, 2017. Sept. 11, 2017: The sun emitted a significant solar flare, peaking at 12:06 p.m. EDT on Sept. 10, 2017. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of the event. 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 X8.2-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. This flare is the capstone on a series of flares from Active Region 2673, which was identified on Aug. 29 and is currently rotating off the front of the sun as part of our star’s normal rotation. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of the events. 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.
