Milne (University of Arizona) report:\n\n\"We observed the field of the short-duration GRB 160410A (Gibson et al.,\nGCN 19271) with the Wide Field Camera (WFCAM) mounted on the 3.8-m United\nKingdom Infrared Telescope (UKIRT) on Mauna Kea beginning on 2016 Apr\n11.215 UT (25.3 hr post-burst). We obtained observations in the J- and\nK-bands in 0.7\" seeing. Using the quick-look pipeline ORAC-DR, we do not\ndetect any near-IR source in or around the positions of the X-ray\n(Beardmore et al., GCN 19273) or optical (Yates et al., GCN 19272; Selsing\net al., GCN 19274; Marshall et al., GCN 19275; Trotter et al., GCN 19277)\nafterglows. Calibrated to 2MASS, we therefore place 3-sigma limits of\nJ(AB)>20.0 mag and K(AB)>19.5 mag on the near-IR afterglow of GRB 160410A\nat 25.3 hr post-burst. We note that this analysis is preliminary and a\nfinal reduction of the images are expected to be ~1.5 mag deeper.\n\nWe thank Sam Benigni for executing these observations. In addition, we\nthank Watson Varricatt, Tom Kerr, and Richard Green for their assistance in\nre-establishing a system for a target-of-opportunity program at UKIRT.\"",
