Another recent animation of solar prominence activity from June 17, 2023. I'm a little disappointed in how this one turned out. It might have been the seeing or more likely my processing.
The animation runs for 32 minutes and consists of 18 frames and ran from 14:25-14:57UT. Notice that this prominence is quite close in the chromosphere. It is only about 10,000 miles high but has a width of roughly 100,000 miles.
For a more detailed explanation about the physics of the activity, I would like to hand that over to my dear friend Andrew Rosado, who is pursuing his PhD in Astro-Physics. He knows way more about the dynamics of what is going on and I hope you find his description interesting and educational. I know I will!
From Andrew:
This is a relatively interesting prominence, it's the most recent animation to present a prominence this low in the chromosphere. To cover a prominence are jets of plasma that are thermally insulated by the magnetic field containing them. As a result, the thermal gradient results in differing optical densities and therefore structure. Despite its relatively low altitude, the prominence is likely relatively cooler than a prominence that reaches out far into the corona. This is a product of the increasing temperature that exists with an increase in distance from the core. At the transition zone, which is about 8500km outwards from the convection zone. Temperatures in excess of 1,000,000 Kelvin.
If you’re interested in a bit more about me and the telescope, feel free to watch a presentation that I gave to The Astro Imaging Channel (awesome site) on YouTube:
