Cobb (GWU) reports:\n\nUsing the ANDICAM instrument on the 1.3m telescope at CTIO, we\nobtained optical/IR imaging of the error region of GRB 160410A\n(GCN 19271, Gibson et al.) with a mid-exposure time of 20.7 hours\npost-burst (2016-04-11 01:49 UT). Total summed exposure times\namounted to 36 minutes in I and 30 minutes in J.\n\nNo source is detected at the position of the optical\nafterglow (e.g. GCN 19271, Gibson et al.; GCN 19272, Yates\net al.) to approximate limiting magnitudes of I > 20.3 and J > 17.5.\nMagnitudes are calibrated using USNO-B1.0 stars in I,\nand 2MASS stars in J.",
