J. van der Horst (GWU) on behalf of the PanRadio GRB collaboration\n\nThe Australia Telescope Compact Array (ATCA) performed observations\nof the long GRB 240712A detected by Swift-BAT (Salvaggio et al., GCN 36851),\nat 5.5, 9, 16.7 and 21.2 GHz as part of the Large ATCA \"PanRadio GRB\"\nfollow-up programme C3542 (PI. Anderson). ATCA start observing on\n2024-07-12 at 4:08 UT (~2 hours post-burst) and continued to observe\nuntil 9:21 UT on 2024-07-12. In our preliminary analysis, we find\nno radio source coincident with the Swift XRT uncataloged source\n(Salvaggio et al., GCN 36851) with 3 sigma upper limits of\n72, 63, 192 and 717 microJy/beam at 5.5, 9.0, 16.7 and 21.2 GHz, respectively.\n\nWe thank the CSIRO Space and Astronomy staff for supporting these\nobservations. We acknowledge the Gomeroi people as the traditional\nowners of the Observatory site. The Australia Telescope Compact Array is\npart of the Australia Telescope National Facility\n(https://ror.org/05qajvd42) which is funded by the Australian Government\nfor operation as a National Facility managed by CSIRO.",
