Pursimo (NOT), report on behalf of a \nlarger collaboration:\n\nWe observed the field of GRB 200528A (Ambrosi et al., GCN 27832) using \nthe Nordic Optical Telescope (NOT) equipped with the ALFOSC camera. \nObservations were carried out under variable, thin clouds. After \nstacking the good images in each filter, no afterglow is visible in \neither band within the XRT position (Evans et al., GCN 27836). At mean \nepochs May 28.926 and 28.927 UT (11.78 and 11.80 hr after the GRB, \nrespectively), we derive limiting magnitudes r > 23.5 and z > 22 AB \n(calibrated against nearby stars in the Pan-STARRS catalog).\n\nWe note that the galaxy visible in the archival surveys and noted by de \nUgarte Postigo & Kann (GCN 27833) is about 10.6 arcsec away of the \nUVOT-enhanced XRT position (1.5\" error; Evans et al., GCN 27836), and is \nthus likely unrelated to the GRB.",
