Iceland), Luca Izzo (DARK/NBI), Amanda Djupvik (NOT), report on behalf of a larger collaboration:\n\nOn 2020 Jan 28.292 UT (16.274 hr after the GRB) we observed the field of GRB200127A (Moss et al., GCN 26895; Evans et al., GCN26902) with the Nordic Optical Telescope in the SDSS r-filter for a total integration time of 900 s. Within the XRT position, we find no evidence for afterglow emission above a 3-sigma limit of about 23 mag AB, calibrated against field stars from the PAN-STARRS catalog.",
