TITLE: GCN CIRCULAR NUMBER: 28915 SUBJECT: GRB 201116A: OSN Afterglow Candidate DATE: 20/11/17 04:36:25 GMT FROM: Alexander Kann at IAA-CSIC A. de Ugarte Postigo (HETH/IAA-CSIC, DARK/NBI), D. A. Kann, M. Blazek, C. C. Thoene, J. F. Agui Fernandez (all HETH/IAA-CSIC), and A. Sota (IAA-CSIC) report: We observed the location of the Swift XRT source #3 found in tiled Swift observations (Evans, GCN #28906), potentially the (X-ray) afterglow of Fermi GBM/LAT GRB 201116A (Fermi GBM Team, GCN #28897; Kunzweiler et al., GCN #28898; Axelsson et al., GCN #28907) with the 1.5m telescope of the Observatorio Sierra Nevada, in Granada, Spain. We obtained 15 x 180 s images in Rc, beginning 2020-11-17 03:24:46.56 UT, 1.1076 days after the GRB. We detect a faint source in the Rc-band stack at (J2000) RA = 09:57:17.94 Dec. = +00:16:34.1 with Rc = 23.18 +/ 0.18 mag (AB), as measured against multiple SDSS comparison stars. This source is not visible in SDSS or PanSTARRS imaging, suggesting it is the GRB afterglow. We cannot determine evidence for fading, however. We wish to congratulate the SpaceX Crew-1 astronauts for their successful arrival at the ISS.
