GREAT (GRond-Epessto-ATlas; ATel #10510) observed this field on June 29, 2017, 01:35 UTC (MJD = 57933.067), nothing detected at the transient position (within the 3.0" circle) with a 3-sigma limiting AB magnitude of r' > 22.8 mag (calibrated against PS1 field stars).

This source is detected in CSS data from 2017-06-14 UT, at V_CSS= 18.0, and
is clearly seen to have significantly faded to V_CSS=18.9 by 2017-06-19 UT.

A source is detected near this location in CSS data at V_CSS ~ 19.0
on 2006-10-10, 2009-08-18 and 2012-06-20. These detections are close
to the discovery magnitude and appear significantly brighter than the
source present in archival PS1 data.
