We do not detected the Swift OT down to the following limits:\n\nFilter (SDSS)  average UT  total Exp (s)  limit (ABmag)\nu            20170828.90    1800    22.5\ng            20170828.89      270    21.6\nr            20170828.88      270    20.8\ni            20170828.93      270    21.9\nz            20170828.92      900    21.4\n\nWe note the presence of the galaxy UGC 1178 at about 5 arcmin from the position of the OT. This galaxy has a redshift z=0.018399, and the projected distance of the OT seen by UVOT would then correspond to about 120 Kpc from the galaxy center.\n\n[GCN OPS NOTE(29aug17):  Per author's request, The Subject-line was changed from \"...INAF Asiago/Copernico...\"\nto \"...GRAWITA Asiago/Copernico...\".
