Florian (U.\nChicago) report:\n\n\"We observed the location of the short-duration GRB 140619B, detected by\nFermi/GBM (Connaughton et al., GCN 16419), Fermi/LAT (Kocevski et al., GCN\n16420), and Suzaku/WAM (Iwakiri et al., GCN 16457) with the FourStar\nInfrared Camera mounted on the Magellan/Baade 6.5-m telescope to cover the\nFermi/LAT position (90% containment; Kocevski et al., GCN 16420). We\nobtained 770 sec of J-band observations on 2014 Jun 20.96 UT (1.48 days\npost-burst). To check for the presence of a fading near-infrared source, we\nre-observed the field (2300 sec) on 2014 Jun 21.97 UT, 2.49 days post-burst\nand 1.01 days after the first set of observations.\n\nDigital image subtraction of the two epochs using the ISIS software package\nreveals no residuals in or around the Fermi/LAT position. We therefore\nplace a 3-sigma limit of J>22.9 AB mag on the brightness of the\nnear-infrared afterglow of GRB 140619B at 1.48 days after the burst.\"",
