Nice Filaprom on The Limb - 5th April

A filaprom is a cross between a filament and a prominence, as a prominence rotates onto the disk, before it becomes a filament outright, as it hovers above both the surface and the limb it is known as a filaprom.  Taken with the 203mm Airylab HaT at 5.6m focal length with a double stacked etalon and the PGR Blackfly GigE IMX249 CMOS camera.
