Sota \n(IAA-CSIC) report:\n\nWe observed the location of the Swift XRT source #3 found in tiled Swift \nobservations (Evans, GCN #28906), potentially the (X-ray) afterglow of \nFermi GBM/LAT GRB 201116A (Fermi GBM Team, GCN #28897; Kunzweiler et \nal., GCN #28898; Axelsson et al., GCN #28907) with the 1.5m telescope of \nthe Observatorio Sierra Nevada, in Granada, Spain. We obtained 15 x 180 \ns images in Rc, beginning 2020-11-17 03:24:46.56 UT, 1.1076 days after \nthe GRB.\n\nWe detect a faint source in the Rc-band stack at (J2000)\n\nRA   =  09:57:17.94\nDec. = +00:16:34.1\n\nwith Rc = 23.18 +/ 0.18 mag (AB), as measured against multiple SDSS \ncomparison stars.\n\nThis source is not visible in SDSS or PanSTARRS imaging, suggesting it \nis the GRB afterglow. We cannot determine evidence for fading, however.\n\nWe wish to congratulate the SpaceX Crew-1 astronauts for their \nsuccessful arrival at the ISS.",
