Tuesdays Fine Prominences! 5th July

A really nice hedgerow prominence visible today, taken with the 0.2 metre Airylab HaT at 5.6m focal length with a double stacked etalon and the PGR Blackfly GigE IMX249 camera.  I suspect by wednesday this will be a filaprom, and by thursday this will be a filament as it moves across the face of the sun.
