SN 2023ixf in M101

The SN is magnitude 14.9 and was classified spectroscopically as a Type II (core collapse) SN. This SN happened about 21m years ago and the light just reached us. It is the closest SN to earth in about a decade.

Here is a side-by-side view of the two very lightly processed data sets. The SN is the bright white star in the top galaxy arm about half way through. It hides the smaller hydrogen region that you can see in the left image.

The image on the left is from Bortle 4 captured on 5/12.
The image on the right is from Bortle 7 captured on 5/20. (not much integration time).

Here is also a report on the SN: https://earthsky.org/todays-image/supernova-in-m101-pinwheel-galaxy-closest-in-a-decade-how-to-see/#:~:text=A%20new%20supernova%20in%20the,telescopes%20for%20a%20few%20months.

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.
