Animation of flares at AR3372 and AR3373 7/16/2023

Acquisition type: Lucky imaging

Captured two decent flares, the first at the very beginning of the animation at AR3373 which was a class C1.55 flare and the second near the very end of the animation at AR3372 which was a class M1.79 and really crushed the histogram. Conditions were poor fighting the smoke from the Canada wildfires. Typically my Hinode Guider will measure the solar intensity at about -2.3 - -2.5 on a sunny morning but on this morning the smoke was so thick that it was measuring around -4.1. Pixinsight did a good job of balancing the variations in brightness except for the last 10 frames when the flare reached maximum brightness and I guess through off PI's readings so there is a bit of darkening at the end. This is 72 minutes in real time. That last flare only lasted 5 minutes.

Title: Close up of flare at AR3372

Description: Highlighting and slowing down the animation of this flare to see the details of the start of the flare. Increased size by 2X so noisy and lacks resolution but shows the structure of the flare as it evolved.

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.
