Quiescent Prominence Bubbles and Dark Plumes

[DeepSolar64]

This is a fantastic movie by Hinode/SOT of a polar crown prominence in Ca H

Woot!

WoW, it looks almost liquid.

In this brief movie of a quiescent prominence, the bright build up of down flow plasma can be seen on the top of the bubble void. The bubble void was quite stable and did not produce dark rising plumes during the period I was imaging.

Figured I would throw this one in from 3/30/2023 showing a developing bubble in the prom on the left (NW limb has been rotated). I should have recorded longer to see if that bubble popped!

Nicely shows how the down flow builds up on top of the bubble. Excellent.

Is this with your double stack system?

Thanks Jim, I thought of you as soon as I saw what I caught! Yes, that is with the Lunt LS60T DS using an ASI174MM and a Meade 3X TeleXtender

A complicated bubble void on the north end of the prominence. Wish the seeing had been better (only rare moments of steady air), would have liked to follow the evolution of that bubble....

These are really quite nice views of it though.

That would have made a great animation

Just came upon this animation from 7/4/2020 which shows a very large “bubble” near the top of this large prom that quickly disappears.
