(CNRS-ARTEMIS) report:\n\nWe imaged the field of GRB 160821A detected by SWIFT\n(trigger 709351) with the TAROT robotic telescope (D=25cm)\nlocated at the Calern observatory, France.\n\nThe observations started 29.31min after the GRB trigger.\nThe elevation of the field decreased from\n10 degrees above horizon and weather conditions\nwere fair.\n\nWe detect a new fading source in the error box given by SWIFT (Siegel et \nal., GCNC 19830) at the following position (+/- 3 arcsec):\n\nRA(J2000.0) = 11h 25m 01.6s\nDEC(J2000.0) +42d 20' 05\"\n\nOT was R~15.4 at 29.31min after GRB. Due to the brightness of the event, \nwe encourage any follow-up.\n\nMagnitudes were estimated with the nearby USNO-B1 stars\nand are not corrected for galactic dust extinction.\n\nN.B. Galactic coordinates are lon=166.5065 lat=+66.7370\nand the galactic extinction in R band is 0.1 magnitudes\nestimated from D. Schlegel et al. 1998ApJ...500..525S.\n\nThis message may be cited.",
