Acquisition type: Lucky imaging

A 35 minute elapsed time animation of small loop proms around a new active area just rotating into view along the southeast solar limb. I unfortunately missed the beginning of the first loop and clouds cut short the animation just as more activity seemed to be occurring. Nevertheless, I was happy to be able to capture the activity shown in the animation. Besides the loops emanating from the solar surface, there was a faint floating prom which also provided movement in the form of coronal rain. Lots of plasma movement all over.

Captured with a Lunt LS80THa (SS), Meade 3x barlow and ASI174MM. Capture sequence was 10 second capture with a 15 second delay. Frame rate was 302 fps which captured over 3,000 frames per SER video. Stacked in AutoStakkert!3, sharpened and aligned in ImPPG, cropped and rotated in PS CC 2022 and PIPP for the animation. The animation covers 1909-1944 UTC.

Seeing was very good throughout the capture sequence. Had a bit of breeze at times which visibly shook the telescope but AS!3 did a great job of stacking.

I had to use JPG files to create an animation that was reasonably sized. Hence, the background in the full resolution shows more noise than I would like.

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.
