M60, NGC 4647, and SN2022hrs

This is another image taken with our new scope during the test phase.

Supernova 2022hrs can be seen in the disk of NGC 4647 (indicated in the zoom-in image). It exploded in mid April 2022 and reached its maximum brightness in early May. We took the images in late May and June. In this period, it appears green, which is the typical behavior of a Type Ia supernova about a month after the maximum. This is caused by the absorption of elements like Fe, Mg, Ca, etc in the blue band, making its green light apparently stronger (than blue). Otherwise, as we all know, there are no regular stars that should appear green.

This image is an LRGB composition. The tri-color part was taken through BVR Johnson photometric filters.

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.
