Object coordinates updated according to AT-report 21889 of Group ZTF
Previous RA, DEC: 18:22:38.070, +12:26:17.66 (275.658625, +12.438239)

We detected a point source in a difference image at the position of AT 2016ewr, with apparent magnitude 19.3 (Clear filter, SNR 2.5) on 2016-08-11T04:49:15 UT, roughly 1 hour prior to the discovery data. We subsequently detected the source on 2016-08-11T23:55:58 UT with apparent magnitude 18.3 (Clear filter, SNR 4). The PROMPT 5 0.4 m telescope was used for both of the observations.
