"Negative" image treatment
Final processing ala Alan Friedman ... the image pixels are "inverted" (imagine a photographic negative).
This shows the prominence areas off the limb in better detail, and you can also see how the rest of the filament/prominence snakes across the photosphere (Sun's visible surface).
The two white spots are sunspots. The very dark squiggles are flaring regions among the sunspots' magnetic fields.
More detailed info is in the comments, below.
