    Complex Eruption on the Sun

    On August 1st, the entire Earth-facing side of the sun erupted in a tumult of activity. There was a C3-class solar flare, a solar tsunami, multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more. Click on the image to view just a fraction of the action: http://science.nasa.gov/media/medial...ngfilament.mov

    The movie recorded by extreme UV cameras onboard the Solar Dynamics Observatory shows an enormous magnetic filament breaking away from the sun. Some of the breakaway material is now en route to Earth in the form of a coronal mass ejection (CME).


    The first of possibly two incoming CMEs hit Earth's magnetic field today at approximately 1730 UT (1:30 pm EDT). As a result of the impact, a polar geomagnetic storm is brewing. High-lattitude sky watchers should be alert for auroras after nightfall.


    Seeing the sun erupt on such a global scale has galvanized the international community of solar physicists. Researchers are still sorting out the complex sequence of events and trying to understand why they all happened at once.

    CME IMPACT: As expected, a coronal mass ejection (CME) hit Earth's magnetic field on August 3rd. The impact, which occurred around 1730 UT, sparked a polar geomagnetic storm. At the time that this alert is being written, sky watchers in Europe as far south as Germany are reporting red and green Northern Lights. If the storm sustains itself for a few more hours, people in North America might see a similar display. Sky watchers in Alaska, Canada, and northern-tier US states such as Wisconsin, Minnesota and Maine should be alert for auroras.

    Fascinating stuff!

    The stupid video doesnt play for me (not even after downloading it... I hate NASA vids)

    The only unedited foto of last night's auroras I could find so far:

    Ein Leben ist nichts, deine Sprosse sind alles
    Aller Sturm nimmt nichts, weil dein Wurzelgriff zu stark ist
    und endet meine Frist, weiss ich dass du noch da bist
    Gefürchtet von der Zeit, mein Baum, mein Stamm in Ewigkeit

    I was excited to get a chance to see the Aurora Borealis again, but unfortunately there was no sightings here in Minneapolis. Too much light pollution.
