Space Weather Imagery of June 22 - 23, 2015 Events

The sun emitted a CME and mid-level solar flare, peaking at 2:23 p.m. EDT, on June 22, 2015. Again on June 25, 2015, a mid-level solar flare peaked at 4:16 a.m. EDT.

NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image 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 first flare is classified as an M6.6 flare and the second was M7.9. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc.
