C. Guidorzi, R. Martone (U. Ferrara), S. Kobayashi (LJMU), C.G. Mundell (U. Bath), A. Gomboc (U. Nova Gorica), I.A. Steele (LJMU), A. Cucchiara, D. Morris (U. of Virgin Islands) on behalf of a large collaboration report: One of the LCO 1-m units at Sutherland Observatory (South Africa) automatically began observing Swift GRB 180715A (Ukwatta et al. GCN 22947) on July 15, 18:17:37 UT (10.5 minutes after the GRB trigger time) with the SDSS r' filter. Within the Swift-BAT error circle, well within the glare of a 8-mag catalogued object we clearly detect a source which is not present in the SDSS catalogue at the following position: RA(J2000)=�� 15:40:22.30 DEC(J2000)= -00:54:44.4 with an error radius of ~1".
