Cosmic Energy Planetary Energy By Ayda Walsh Share Tweet Share Share An expert has warned that a solar flare is going to hit “any day” now, and Earth’s technology could suffer tremendously. Check out Richard A Lovett reports here. What are Solar Flares? Solar flares are eruptions of energy from the Sun which spew out into the cosmos. A flare is defined as a sudden, rapid, and intense variation in brightness. A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. Radiation is emitted across virtually the entire electromagnetic spectrum, from radio waves at the long wavelength end, through optical emission to x-rays and gamma rays at the short wavelength end. The amount of energy released is the equivalent of millions of 100-megaton hydrogen bombs exploding at the same time! Info source When Was The Last Time Solar Flares Hit The Earth? The solar storm of 1859 (also known as the Carrington Event) was a powerful geomagnetic storm during solar cycle 10 (1855–1867). A solar coronal mass ejection (CME) hit Earth’s magnetosphere and induced one of the largest geomagnetic storms on record, September 1–2, 1859. WATCH : What If Earth Was Hit By A Giant Solar Flare?
