Solar Physicists Still Trying to Figure Out What Happened on the Sun


“Earth-orbiting satellites detected a flash of X-rays coming from the western edge of the solar disk. Registering only ‘M’ (for medium) on the Richter scale of solar flares, the blast at first appeared to be a run-of-the-mill eruption–that is, until researchers looked at the movies.

NASA has just released new high-resolution videos of the event recorded by the Solar Dynamics Observatory (SDO). The videos are large, typically 50 MB to 100 MB, but worth the wait to download…

‘IN terms of raw power, this really was just a medium-sized eruption,’ says Young, ‘but it had a uniquely dramatic appearance caused by all the inky-dark material. We don’t usually see that.’

Solar physicist Angelos Vourlidas of the Naval Research Lab in Washington DC calls it a case of ‘dark fireworks.’

‘The blast was triggered by an unstable magnetic filament near the sun’s surface,’ he explains. ‘That filament was loaded down with cool1 plasma, which exploded in a spray of dark blobs and streamers.'” Source.
