Filament erupts and XRT sees post eruption loops (click on image to see movie)
|
The above movies show the evolution of the solar corona over 15 hours near the
north pole of the sun in two filters (Al_poly left, Ti_poly right).
The limb of the sun is visible at the top of the image. Dark
regions on the disk of the sun show areas where the sun's magnetic field
extends into space. Small bright regions (called X-Ray Bright Points) are associated
with compact magnetic fields. The intermediate areas show plasma trapped in
larger closed magnetic fields in the so-called quiet sun. As the movie runs you will
see numerous jets in the polar region and around frame 320 a bright line of loops
forms near the middle of the FOV. This is likely to be the result of a polar crown
filament that erupted. The arch of loops is similar in shape and duration to those
seen after large flares, because they result from the same underlying physical process:
the closing down of magnetic field lines after an eruption. Question for the viewer:
Are the post eruption loops overlying the filament channel or are they only on
near side?
