NASA's SDO sees mid-level solar flare

The sun emitted a mid-level solar flare, peaking at 4:16 a.m. EDT on June 25, 2015. 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 flare is classified as a M7.9 flare. 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.

Van Allen belts protection is like a Divine gift by Nature. It s an appeal to all scientists to save Earth Planet and Life support.
please do not destroy outer or inner van Allen belts through ionosphere heating.
Any such attempt boomerangs on living Earth with catastrophes like unwanted climate changes and environmental effects.
