NGC 4216 & Co with supernova SN 2024gy

The Japanese amateur astronomer Koichi Itagaki discovered the supernova SN 2024gy in NGC 4216 on January 4, 2024 (marked below). Before that he had accomplished the incredible feat of discovering more than 170 supernovas. At that time it was still quite dim but later increased in brightness. My image shows that it is still clearly visible.

Most images I have seen of these galaxies are RGB images. I thought it would be worthwhile to also collect some Ha, so this is a HaLRGB image revealing quite a bit of Ha regions in the galaxies.

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.
