NASA’s SDO Sees Third Summer Solar Flare On June 11

UPDATE – June 11, 2014

On June 11, 2014, the sun erupted with its third X-class flare in two days. The flare was classified as an X1.0 and it peaked at 5:06 a.m. EDT.  Images of the flare were captured by NASA’s Solar Dynamics Observatory. All three flares originated from an active region on the sun that recently rotated into view over the left limb of the sun.

UPDATE – June 10:

The sun released a second X-class flare, peaking at 8:52 a.m. EDT on June 10, 2014.  This is classified as an X1.5 flare. (See second image below)

The sun emitted a significant solar flare, peaking at 7:42 a.m. EDT on June 10, 2014. NASA’s Solar Dynamics Observatory (SDO) – 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 by NASA as needed.

Image 3 (below):  The second X-class flare of June 10, 2014, appears as a bright flash on the left side of this image from NASA’s Solar Dynamics Observatory. This image shows light in the 193-angstrom wavelength, which is typically colorized in yellow. It was captured at 8:55 a.m EDT, just after the flare peaked. Credit: NASA/SDO
