AT2018gci, Type unknown in Mrk 359
Discovered 2018/09/01.472  by ZTF, mag 17.99 at discovery
R.A. = 01h27m32s.530, Decl. = +19°10’43”.85

Approx mag 14.67CV ±0.00, ZP=28.719mag
Note: the coordinates provided are that of the core of Mrk 359 which is reported at 14.22V. It’s difficult to see how a 17.99mag event could be see at those coordinates.

AT2018glx, Type unknown
Discovered 2018-09-12.458 by Gaia, mag 18.19 at discovery

Approx mag 19.57CV ±0.03, ZP=29.392mag
Note: the coordinates are that of Gaia DR2 1930770116620267136 which is reported at mag 19.21g. Given the difference ni mag compared to discovery and the existing object’s mag, it’s doubtful anything other than the pre-existing object is visible.
