(UVI - Etelman Obs.) report:\n\nWe imaged the field of GRB 160506A detected by SWIFT\n(trigger 685245) with the TAROT robotic telescope (D=25cm)\nlocated at the European Southern Observatory,\nLa Silla observatory, Chile.\n\nThe observations started 62.1s after the GRB trigger\n(14.0s after the notice). The elevation of the field increased from\n41 degrees above horizon but clouds were presents in the sky.\n\nThe first image is trailed with a duration of 60.0s\n(see the description in Klotz et al., 2006, A&A 451, L39).\nWe do not detect any OT with a limiting magnitude of:\nt0+62.1s to t0+122.1s : Rlim = 12.7\n\nThen the observations were stopped due to the bad weather\nand start again 39 minutes later. We co-added a series\nof exposures:\nt0+2366s to t0+3314s : Rlim = 16.7\n\nMagnitudes were estimated with the nearby NOMAD1 stars\nand are not corrected for galactic dust extinction.",
