Something strange here. The last recorded supernova in M81 was in 1993,
supernova SN 1993J. This is a good example:

Certainly not visible now. And there are a number of stars in the image
which don't appear in images I've examined including my most recent one

So either we have an amazing number of sudden outbursts, or more likely
there's something wrong with the image.
