Nova M33 2022-11a

Discovered at mag 13.4 apparently in M33. I wonder what it is? Too bright for a regular nova in M33 (that would be more like mag 17).

Word is that whatever it was, it's back down at mag 16 or so now. https://www.physics.purdue.edu/brightsupernovae/novae.html#NM332211a

It looks to be at the location of a  red object in images  but from the list of references apparently also appears in X ray source catalogues. Described as a globular cluster candidate in SIMBAD, though the note there suggests contradictory descriptions in the literature.

Previously catalogued at Vmag 17.3 so a ~4 mag brightening.
