Having just seen this APOD and clicking on the SDO's current image link the filament still seems to be there. Here is that then current image's url link:- http://sdo.gsfc.nasa.gov/assets/img/lat ... 4_0304.jpg

So now we know where our "sun" came from :roll: And are the girls just as bright? Of course - they brought on delight! :yes:

The magnetic field is closed, so we're just looking down on a prominence. It hasn't resulted in much material being thrown away from the Sun. It might yet. Or not.

Not 93000000 million but it scared the bjesus out of me.
Right. As compared with the Sun's radius of 432,000 miles.

Looks familiar.

Looks like in the movie ( http://sdo.gsfc.nasa.gov/data/dailymov/ ... _1024_0304 ) this is three filaments. From the right, there is a dog-leg left and a dog-leg right. Nice plasma bounces between the nodes.

Image An Extremely Long Filament on the Sun

Explanation: Yesterday, the Sun exhibited one of the longest filaments ever recorded. It may still be there today. Visible as the dark streak just below the center in the featured image, the enormous filament extended across the face of the Sun a distance even longer than the Sun's radius -- over 700,000 kilometers. A filament is actually hot gas held aloft by the Sun's magnetic field, so that viewed from the side it would appear as a raised prominence. The featured image shows the filament in light emitted by hydrogen and therefore highlights the Sun's chromosphere. Sun-following telescopes including NASA's Solar Dynamics Observatory (SDO) are tracking this unusual feature, with SDO yesterday recording a spiraling magnetic field engulfing it. Since filaments typically last only from hours to days, parts of this one may collapse or erupt at any time, either returning hot plasma back to the Sun or expelling it into the Solar System. Is the filament still there? You can check by clicking on SDO's current solar image.
