Zhao, J. Bai, C. Wang, Y. \nXin (Yunnan Observatories of CAS), on behalf of a larger \ncollaboration, report:\n\nFollowing the detection of SGR Swift J1818.0-1607 by Swift (Evans et al. \nGCNC 27373), the 0.6m BOOTES-4/MET robotic telescope at Lijiang \nAstronomical Observatory (China) gathered images starting at 21:17:34 UT \n(47 s after trigger). No optical afterglow is found down to 19.3 mag (in \nco-added 10x10 s unfiltered images) within the Swift/XRT error box, \nconsistent with the non-detection by Swift/UVOT (Evans et al. GCNC \n27373). Further observations are ongoing.\n\n[GCN OPS NOTE(14mar20): Per author's request, Y.Xin's affiliation was changed\nfrom \"Yunnan Nacional Astronomical Observatory\" to \"Yunnan Observatories of CAS\".]",
