Filaprom on the Western Limb
Explanation: A solar filament is an enormous stream of
incandescent plasma suspended above the
active surface of the Sun by looping magnetic fields. Seen against the solar disk it looks dark only because it's a little cooler, and so slightly dimmer, than the
solar photosphere. Suspended above the solar limb the same structure looks bright when viewed against the blackness of space and is called
a solar prominence. A filaprom would be both of course, a stream of magnetized plasma that crosses in front of the solar disk
and extends beyond the Sun's edge. In this
hydrogen-alpha close-up of
the Sun captured on June 22,
active region AR3038 is near the center of the frame. Active region AR3032 is seen at the far right, close to the
Sun's western limb. As AR3032 is carried by
rotation toward the Sun's visible edge, what was once a giant filament above it is now partly seen as a prominence, How big is AR3032's filaprom? For scale planet Earth is shown near the top right corner.

I in honest have tried to imagine a link between the filaprom and any feature on the surface.
None worked

This kind of picture of the sun always reminds me of shelled corn!

The "
AR3032's filaprom" link in the caption takes you to a really impressive video of this "filaprom".

Thanks
They call it AR303
8, not AR303
2
The time-laps covers 45 minutes of real time, too short for Sun's rotation to let us observe the 3D position of the filaprom
Is it invisibly connected to AR303
8, to AR303
2, to both, to none?…

a roll cloud can be a smooth border of an air mass and so may do without a strong magnetic connection to any spots on Earth's surface

AR3038 (center) and AR3032 (far right) don't look to be connected at all. And the filaprom would seem to be related to AR3032 alone.
