Jakobsson (U Iceland) report on behalf a larger collaboration:\n\nWe observed the field of the short GRB 160601A (Kocevski et al., GCN 19478) with the Nordic Optical Telescope (NOT) equipped with the AlFOSC imager. Our first 900-s exposure in the r band started on Jun 1.885 UT (6.5 hr after the GRB).\n\nClose to the UVOT-enhanced XRT position (Evans et al., GCN 19484), we detect two sources, at coordinates:\n\n(1)\nRA = 15:39:43.97\nDec = +64:32:30.5\nr mag = 22.85 +/- 0.10 (AB)\n\n(2)\nRA = 15:39:44.91\nDec = +64:32:32.1\nr mag = 23.04 +/- 0.09 (AB)\n\nVisual inspection of the SDSS at the above locations shows a faint, marginally detected object coincident with source (2), but no object at the position of source (1). We thus consider source (1) to be a potential afterglow candidate, though further observations are needed to test its variability.",
