The possible supernova appears to be on the south-west of NGC 5363 and very close to the galaxy core. It's not shown up in WIKISKY or the Digitized Sky Survey. Estimated magnitude to be ~13.5 to 14.5 based on comparison to similar bright stars nearby. Reported by Philip Hoyle and assigned as AT 2020leu but seems with different RA/DEC coordinate.
