The Sun Unleashes Coronal Mass Ejection At Earth

astroengine writes "Yesterday morning, at 08:55 UT, NASA's Solar Dynamics Observatory detected a C3-class flare erupt inside a sunspot cluster. 100,000 kilometers away, deep within the solar atmosphere (the corona), an extended magnetic field filled with cool plasma forming a dark ribbon across the face of the sun (a feature known as a 'filament') erupted at the exact same time. It seems very likely that both eruptions were connected after a powerful shock wave produced by the flare destabilized the filament, causing the eruption. A second solar observatory, the Solar and Heliospheric Observatory, then spotted a huge coronal mass ejection blast into space, straight in the direction of Earth. Solar physicists have calculated that this magnetic bubble filled with energetic particles should hit Earth on August 3, so look out for some intense aurorae — a solar storm is coming."

    Do they mean it's traveling a straight line? Or do they mean it's is moving in such a way so as to collide with us when we come around to a certain point in space?

    Unless they hit Germany and the radioactive wild pigs become sentient, hack into the EU's carbon trading system and make enough money to buy their own Island near the island of Doctor Moreau.

    It's not ironic in the slightest for a solar-orbiting satellite to get knocked out by a coronal mass ejection. That's exactly what one would expect to happen. There's no reversal of expectations whatsoever, unless you expect that a solar observatory is somehow also a solar defense shield.

    Irony is not the most straightforward and expected series of events. SOHO detects mass ejection. SOHO gets hit by it. SOHO dies.

    Irony is you linking to a post that actually proves my point, but then points out what a dork I am for arguing it. :P
