Iceland) report on \nbehalf of a larger collaboration:\n\nWe observed the field of GRB 160123A (Malesani et al., GCN 18926) with \nthe Nordic Optical Telescope (NOT) equipped with the NOTCam \nnear-infrared camera. Observations were carried out in the J filter. Sky \nconditions were not optimal, with moonlit clouds and a seeing of 1.7\". \nThree sets of nine images by 1 minute each were acquired, starting on \nJan 24.067 UT (16.6 hr after the GRB).\n\nAfter stacking the best 18 images, no source is detected within the XRT \nlocalization area (Beardmore et al., GCN 18927; see also \nhttp://www.swift.ac.uk/xrt_positions/00671447/), down to a limiting \nmagnitude J > 19.5 (Vega), calibrated against the 2MASS catalog.",
