Hovering Filaments - 7th April

Filaments are huge clouds of cool plasma held above the suns surface by magnetic fields.  The huge solar clouds can hang around for days or weeks at a time before sometimes just gradually dissipating and drifting away, or sometimes being thrown from the sun more dramatically as the magnetic field lines snap explosively and dramatically.  As they rotate over the suns limb they form a filaprom before finally a prominence as they rotate out of view over the limb.  This image was taken with the DS Quark, 100mm f10 Tal100R refractor, 0.6x focal reducer and an Imaging source DMK31 camera.
