"On April 2, 2014, the sun emitted a mid-level solar flare,
peaking at 10:05 a.m. EDT, and NASA’s Solar Dynamics Observatory
captured imagery 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 whereGPS
and communications signals travel.
To see how this event may impact Earth, please visit NOAA’s Space
Weather Prediction Center, the U.S. government’s official source for
space weather forecasts, alerts, watches and warnings.
This flare is classified as an M6.5 flare. M-class flares are ten times
less powerful than the most intense flares, which are labeled X-class.
The number after the M provides more information about its strength. An
M2 is twice as intense as an M1, an M3 is three times as intense, etc."
