Comments

We have observed this object last night and found it at 13.63 ±0.01 mag (URAT-1 V magnitude unfiltered) in a stack of 48x20s exposures.

This is consistent with the brightness of 13.8-13.9 mag reported by ASASSN (in a different colour band). ASASSN have seen it at this brightness since at least June 2016 (see https://asas-sn.osu.edu/light_curves/b7c12a4e-1fe7-4f13-beec-2868267e01c4).

The star is present at the same brightness in the USNO-A2.0 catalog, as USNO-A2.0 0975-18641686 at epoch 1953.682 (see http://vizier.u-strasbg.fr/viz-bin/VizieR-5?-ref=VIZ5b69ef4ba748&-out.ad...), and also in several other star catalogs.

This all indicates that 2016ero is not a transient, and probably not even a variable.
