TITLE: GCN CIRCULAR NUMBER: 13180 SUBJECT: GRB120327A - ATCA radio afterglow detection at 34GHz DATE: 12/03/31 21:01:15 GMT FROM: Paul Hancock at U of Sydney P. Hancock, T. Murphy, B. Gaensler, M. Bell, D. Burlon (University of Sydney/CAASTRO), A. de Ugarte Postigo (Dark Cosmology / IAA) We observed GRB120327A (GCN13123) with the Australia Telescope Compact Array for 40 mins centered on 17:55UT on March 31 2012 (T0+4.625days). We find an unresolved radio source at ra=16:27:27.4, dec=-29:24:54.0 with a flux of 0.72+/-0.03 mJy. This position is consistent with the optical position of GCN13138. Further observations are planned. These observations were obtained as part of ATCA project C2689. We thank the observatory staff for their support and scheduling the observations. The Australia Telescope is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO.
