Sun H Alpha: Animation of prom on 2022-03-13 09:22 to 12:27 UTC

Acquisition type: Lucky imaging

Hello Friends,

this time a new animation of today's Prom. This time it is 50 frames in an interval of 180s. Also I have tried some new processing techniques. E.g. the automatic blackening of the sun disk during capture in FireCapture.

Some frames are blurry due to high clouds, but I have decided to keep them, because otherwise the animation would jump - and this is even worse.

Interesting in this animation is to see, that some plasma streams do or seam to revert their flow direction. First I thought i have messed up the frame sequence and triple checked it, but it is really reversing.
Others are an optical phenomena since the clouds rotate around an upright axis - like an tornado. So when the rotate on the backside compared to the front side it looks like they are suddenly reversing.

Some are also floating back and forth. Like waves.

There are many dynamic effects to discover.

Please enjoy!
Rüdiger

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.
