Scientists now believe that our Sun is capable of producing a type of powerful and disruptive ‘superflare’.
The latest 11-year cycle of the sun is almost over and scientists have just released predictions for the next one.
On Feb. 24th, a magnetic filament on the sun became unstable and erupted. The blast hurled a coronal mass ejection (CME) into space. NOAA analysts have modeled the expanding storm cloud, and they say it will miss Earth. No geomagnetic storm will result from the explosion.
10 times brighter than any flares from our Sun.
The sun blasted out seven massive solar flares in as many days in an extraordinary period of space weather that has sparked stunning geomagnetic storms above the earth.
On Sept. 10th, departing sunspot AR2673 erupted, producing a powerful X8-class solar flare. The explosion propelled a CME into space and accelerated a swarm of energetic protons toward Earth. Both are visible in this coronagraph movie from the Solar and Heliospheric Observatory (SOHO): The many specks in this movie are not stars–they are solar protons
If you still have your solar viewing glasses from the eclipse, now is a good time to slap them on and look up at the sun.
On Sept. 6th at 1202 UT, sunspot AR2673 unleashed a major X9.3-class solar flare–the strongest solar flare in more than a decade. X-rays and UV radiation from the blast ionized the top of Earth’s atmosphere, causing a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean: Link to blackout map.

It is possible that a superflare could happen from our Sun, and if Earth is in the line of fire, it could very well end the world.
