Supernova SN2023ixf - M101 Pinwheel Galaxy

I spotted this in the news and forums, so thought I'd try to image it. It's a first for me!

Discovered 2 days ago by Japanese amateur astronomer Koichi Itagaki. SN2023ixf is a type II supernova, which is caused by a massive star's core collapse and subsequent explosion. At around 21 million light years away, it's the closest supernova in a decade and unusually bright, which means it can be observed with our amateur size telescopes.

Even though the sky quality was poor, it was clearly visible in single 10 second exposures. I measured it at magnitude 12.1 and it could get much brighter over the next few days!

Clear skies!

Tony.

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.
