A solar flare is a violent explosion in a star's (like the Sun's) atmosphere releasing up to a total energy of 6 × 1025 Joules.[1] Solar flares take place in the solar corona and chromosphere, heating plasma to tens of millions of kelvins and accelerating electrons, protons and heavier ions to near the speed of light. They produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths from long-wave radio to the shortest wavelength gamma rays.[2] Most flares occur in active regions around sunspots, where intense magnetic fields emerge from the Sun's surface into the corona. Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona.

X-rays and UV radiation emitted by solar flares can affect Earth's ionosphere and disrupt long-range radio communications. Direct radio emission at decimetric wavelengths may disturb operation of radars and other devices operating at these frequencies.

Solar flares were first observed on the Sun in by Carrington and independently by Hodgson in 1859 as localized brightenings in a sunspot group. Stellar flares have also been observed on a variety of other stars.

The frequency of occurrence of solar flares varies, from several per day when the Sun is particularly "active" to less than one each week when the Sun is "quiet". Large flares are less frequent than smaller ones. Solar activity varies with an 11-year cycle (the solar cycle). At the peak of the cycle there are typically more sunspots on the Sun, and hence more solar flares.

  • First destructive solar flare was recorded in 1859. Telegraph poles were on fire and telegraph network were down. After careful study, next event was already foreseen with 90% life wipe out but Scientist coded the actual date in Religious way to prevent people from panicking (late 19th century). Micheal the Archangel was the key where he defeated Satan and save the Earth from burning in Hell. 2012 - 1859 = 153.

    Search 153 that relates "Micheal the Archangel" in Google. You'll be surprised.

  • @Stryker1211 im sorry to say unpluging it from the wall wont help,it must be surrounded by aluminum foil or in a metal pot,and if you can grounded

  • The Currency. LOL. 

  • @dave777blaster he was meaning that he would unplugg his shit so it doesn't, oh, i donno, BLOW UP IN HIS FACE?

    just saying.

  • the sun farted

  • It's about time the human race was wiped out anyway

  • mmmm sex in the heat

  • Im unplugging all my shit from the wall

    lol

    what an ignorant statement

    it would fry all electrical items plugged in or not
