Veilleux (UMD), report on behalf of a larger\ncollaboration:\n\nWe observed the field of the GRB 201014A (Ambrosi et al., GCN 28623)\nusing the Large Monolithic Imager (LMI) on the 4.3m Lowell Discovery\nTelescope (LDT) at Happy Jack, AZ. Observations started on October 16,\n07:08:10 UT (1.35 days after the Swift trigger) taking 4 exposures of\n175 s each with SDSS i and SDSS r filters. Observations were taken\nat an airmass of about 1.01 and seeing of about 1.7\".\nWe detected the optical transient (Pozanenko et al., GCN 28628; de Ugarte\n Postigo et al, GCN 28650) inside the enhanced XRT position (D'Elia et al.\nGCN 28626) measuring the following AB magnitudes: i=22.75 +- 0.07 and\nr=24.30 +- 0.12.\n\nMagnitudes are calibrated against the SDSS catalog and not corrected\nfor Galactic extinction.\n\nThe r/i drop-out is consistent with the high-z measured from GTC\n(de Ugarte Postigo et al, GCN 28650).\n\nWe thank the staff of the Lowell Discovery Telescope and Quanzhi Ye for\nassistance with these observations.\n\n[GCN OPS NOTE(18oct2020): Per author's request, the Title \"GRB 201014A: Lowell Discovery Telescope upper limits\"\nwas changed to \"GRB 201014A: Lowell Discovery Telescope afterglow imaging\".]",
