Moderate flare AR 3176 Dec 30 2022

Acquisition type: Lucky imaging

I noticed a flare in AR 3176 while imaging the Sun on Friday, Dec 30, 2022. I was not fortunate enough to catch the start but caught the tail end of the flare. As I was imaging, I received an alert from Spaceweather.com of a Moderate M3.74 flare at 1954 UTC. Equipment was a Lunt LS80 THa (single stack), TeleVue PowerMate 2.5x and ASI174MM camera. My animation runs from 1935 - 2001 UTC. According to Spaceweather.com this flare hurled a CME toward Earth. Expected arrival is Jan 4, 2023.

I stopped the capture as I was getting horizontal bands ranging from thin lines to relatively thick bands. This behavior has just started the last few times imaging using FireCapture. The initial videos are fine but after a bit, the horizontal banding starts and becomes more and more prevalent as time goes on. I used the Row Noise Correction feature in AutoStakkert!3 while stacking but that didn't completely solve the problem as can be seen by flickering along the bottom of the last few frames of the animation. Interestingly, I can switch to SharpCap and the banding stops.

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.
