Sun Produces Strongest Flare Ever Recorded 422

      Highly unlikely. The heat from the Sun would vaporise anything long before impact.

      Flares (including this one) tend to be linked with sunspots which are relatively cool (emphasis on the relatively there) areas of the Sun. The Sun is made of plasma - super-hot electrically-charged particles. The plasma convects, transferring energy to the surface of the Sun. As the plasma moves it creates enormous magnetic fields. Normally these are confined within the body of the Sun, but occasionally, the magnetic flux extends beyond the surface of the Sun as an enormous loop. At each point where the line emerges and re-enters the Sun are a group of sunspots.

      Hot plasma streams along the line of flux, it usually confined to the magnetic flux, but occasionally it will break away as a so-called prominence.

      Flares are relatively common, but their cause is not yet understood (if any solar activity experts are hanging around - please feel free to step in right about now :)). From memory, the most well-regarded theory is that ever-increasing amounts of energy is stored in the magnetic fields of the sun spot. As the field becomes twisted and tangled, the energy continues to build until a point when the magnetic field snaps back into a less-tangled state. At that point an enormous amount of energy and plasma are blasted into space in a very short period of time.

      Best wishes,
      Mike.

    • The area of sunspots responsible for this latest spat of solar activity are FIFTEEN TIMES THE SIZE OF THE EARTH. Just to make this perfectly clear, THE SUN IS FUCKING HUGE! The whole fsking EARTH could smash into it and the sun wouldn't even blink. So no, it's highly unlikely that some heavenly body about 100 times the size of Jupiter smashed into the sun and we didn't see it coming or notice it happening. Solar weather just goes through weird phases, just like earth weather. That's all.

    Craig DeForest, a solar physicist at the Southwest Research Institute, said others in his field are discussing the possibility that Tuesday's flare was an X40.

    "I'd take a stand and say it appears to be about X40 based on extrapolation of the X-ray flux into the saturated period," DeForest told SPACE.com.

    That estimate may even be conservative, he said

    x40.. holy crap.. and that number might be low

        X-Ray flux is measured in Watts per square meter (averaged out over a period of time, usually over a minute).

        10^-8 is the lower threshhold of an A-Class
        10^-7 is the lower threshhold of a B-Class
        10^-6 is the lower threshhold of a C-Class
        10^-5 is the lower threshhold of a M-Class
        10^-4 is the lower threshhold of a X-Class
        10^-3 is the lower threshhold of a X10-Class
        10^-2 would be the lower threshhold of an X100-Class

        So, the X-28 flare saturated the detectors of the GOES satellites with 0.0028 W/m^2 energy.

Maybe the sun is made of iron instead of hydrogen [pairlist.net] where would all the theories that say we are safe be then, if such a basic 'fact' about the sun turned out to be wrong?

    The power of these flares spewing into space must be truly ginormous. Sure, they're unusual, and unpredictable. But if we could harness even a tiny fraction of even a single one, we could supply all the Earth's energy needs for the forseeable future.

    How about we send a bunch of satellites into LSO (low solar orbit), within the orbit of Mercury, with solar photocollectors powering their wait. When a flare does come by one or more of them, a large, diaphanous electromagnetic antennae are charged by the approaching particle storm, converting the power into electricity, which charges a laser array. The lasers fire from the "lucky" satellite into a power grid among all the satellites. The satellites nearest the Earth fire the power at a receiver on the Moon, which charges a gigantic battery bored beneath the surface. Over months or years, lower powered lasers send the power to collector platforms floating on the seas, which send electricity over cables to the electric grid on land.

    Sure, we'd have to wait years before a flare was captured. And it likely would destroy at least one of the satellites capturing it. But there would be several seconds during which the satellite could capture more joules of power than consumed since we invented fire. So after a patient wait, playing the odds, we'd win the solar lottery. If we started now, repurposing all that expensive, dead-end Star Wars spacewar technology, we might be ready by 2020. Then we could power not just our homey little Earth, but all our exploration/communication needs within the planetary systems.
