Burlon (University of\nSydney/CAASTRO), A. de Ugarte Postigo (IAA-CSIC, DARK/NBI)\n\nWe observed GRB121217A (GCN 14809) with the Australia Telescope\nCompact Array at 44GHz for 90 minutes centered on 12:55UT Dec 21 2012\n(T0+4.234days) in poor weather.\n\nWe detect no radio source at the optical location of the GRB (GCN\n14091) and place a 3sigma upper limit of 0.6mJy on the flux of an\nafterglow.\n\nThese observations were obtained as part of ATCA project C2689. We\nthank the observatory staff for their support and scheduling the\nobservations. The Australia Telescope is funded by the Commonwealth of\nAustralia for operation as a National Facility managed by CSIRO.",
