Revision title: NGC4647 before and after SN2022hrs

I was lucky enough to take images of M60 and NGC4647 before and after the eruption of the supernova SN202hrs.
Here is a side by side comparison with just one month in between the two images. The eruption of SN2022hrs was detected on 16th April 2022 by Koichi Itagaki with a brightness of 15.0mag. 12 days later, when I took my image I measured 12.7mag, which was very close to the maximum brightness that the SN reached. The latest images at the end of July show a brightness of 15-16mag. It's great to see astrophysics in action ...

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.
