GCN Circular 12664
Paul J. Hancock, Tara Murphy, Bryan Gaensler (U of Sydney), Ashley Zauderer (Harvard) On the 11th December 04:44-05:50UT (T=+1.9days) we observed GRB 111209A (GCN12632) with the Australia Telescope Compact Array (ATCA) at 34GHz. We do not detect any radio emission consistent with the GRB optical position (GCN12642). We place a 3sigma upper limit of 132uJy on the flux of the afterglow. Further observations are planned. We thank the staff of the ATCA for their help in organising these observations.
