Details:
Remember the big prominence on the NE limb for last few days? Now rotated onto disk as a huge dark filament, with a "filaprom" visible connecting limb to disk. Prominences glow red at about 4000K, so appear bright hanging out over limb. But against the 5800K photosphere, they re cooler and darker, hence appear as filaments like this. Lunt 60, B 1200 Ha diagonal, 12 mm Plossl, and iPhone 6s.
