This image is the centre portion of a huge solar filament that extended for over 100 kilometres across the sun's surface. This is just the centre portion at higher magnification so as to see structure. The ribbon extends almost an equivalent amount in either direction from this frame.

A series of quite complex prominence structures in this image.

Bridging prominence taken at 5.30pm on 25th March 2012.

A composite image in H-Alpha showing both prominence and surface detail.
