AT 2020tui is likely galactic variable/outburst

AT2020tui is coincidence with a G = 19.33 Gaia source, which appears red in PS1 data. The low galactic latitude and association with what appears to be Galactic diffuse emission imply this is almost certainly a Galactic variable or outburst and not a SN candidate.
