Explosive Prominence Nov 18, 2020

Acquisition type: Lucky imaging

A 76 minute elapsed time animation of an interesting prominence on the NE solar limb Wednesday, Nov 18, 2020. Captured between 11:49 CST/1749 UT and 13:06 CST/1906 UT. About 10 minutes into the capture, a small surge prominence interacts violently with a descending leg of an arch prominence. Plasma seems to shoot in two directions (due to our line of sight) while material continues up through the arch leg splitting it into two legs, each of which subsequently reconnect to the Sun's surface.

Seeing was generally good but there were a few periods of poor seeing, perhaps from high thin clouds that I was not able to see. The edge of the Sun would ripple significantly as I have seen other times before clouds. I have removed a few of the blurred images to make the animation smoother.

I captured 15 second videos with a 15 second interval between captures using SharpCap Pro. The video captures were stacked in AutoStakkert 3, sharpened and aligned in ImPPG and the black occulting disk was added in Photoshop CC 2019. PIPP was used to make the final animation.

The Final version is at 20 fps. Version B is a slower version at 10 fps.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
