There has been a visible star at that location for a while. I found it in my archives on 2018-08-06.104. It was then approx mag 17.36. It was 18.39 yesterday.
Indeed, I also have some images taken a few minutes before the first photometric measure of this report. There was no transient down to magnitude 18.5 fifty minutes before. https://www.flickr.com/photos/econseil/30326201698

ATel #11983
Liverpool telescope reports this candidate as "source detected - - too faint" for astrometry. Are the images available? I can't find them.
