Ludwig (all TLS Tautenburg) report:\n\nWe observed the field of the short GRB 160408A (Evans et al., GCN\n19260) with the Tautenburg 1.34-m Schmidt telescope at as mid-time of about\n15.3 hrs after the GRB trigger, at a mean airmass of 1.2. We obtained 10 x\n300 sec exposures in the Ic band.\n\nInside the 1\".9 enhanced XRT error circle (Osborne et al.,GCN 19261),\nwe do not detect the possible optical counterparts reported by Levan et\nal. (GCN Circ. 19262). We estimate a preliminary upper limit of Ic > 21.3\nmag, calibrated against USNO-B1 field stars.\n\nThese observations were performed as part of the Tautenburg Observing\nSchool at the Thueringer Landessternwarte.\n\n[GCN OPS REPORT(14apr16):  Per author's request, the institutional affiliations\nof the authors was corrected, and the last sentence was added.]",
