Veilleux (UMD), report on behalf of a larger\ncollaboration:\n\nWe observed at the position of the optical transient ZTF20abwysqy reported\nby Ahumada el al. (GCN Circ. 28287) as a possible afterglow candidate for\nGRB 200826A (Fermi GBM team, GCN 28284, Mangan et al., GCN Circ. 28287)\nand coincident with the X-ray Source 3 reported by D'Ai et al. (GCN Circ.\n28300). We use the Large Monolithic Imager (LMI) on the 4.3m Lowell\nDiscovery Telescope (LDT) at Happy Jack, AZ. Observations started on\nAugust 29, 10:04:56 UT (3.23 days after the Fermi trigger) taking 8\nexposures of 180 s each with SDSS r filter. Observations were taken at an\nairmass of about 1 and seeing of 1.4\".\n\nWe detect the underlying galaxy reported by Ahumada el al. (GCN Circ.\n28287) with magnitude r=22.60 +/- 0.03 AB mag. We do not find any other\nsource at the reported position down to a 3-sigma field limit of r>24.5\nAB mag.\n\nMagnitudes are calibrated against the SDSS catalog and not corrected for\nGalactic extinction.\n\nWe thank the staff of the Lowell Discovery Telescope for assistance with\nthese observations.",
