The third and last supernova beside SN 2021biz and SN 2021do.
To the moon here came some light pollution from the street. I never had so much trouble to get this out of a picture. This resulted in an immense loss of color, I think. But I couldn't have processed the image much better.
There are few wide angle images of M81 with this galaxy, so I assume this is also a debut.
More data to the SN itself here.
