J. van der Horst (GWU) on behalf of the PanRadio GRB collaboration\n\nThe Australia Telescope Compact Array (ATCA) performed observations\nof GRB 240222A (Fermi GBM Team, GCN 35769; D'Avanzo et al., GCN 35770)\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 observed from\n2024-02-24 12:00 UT to 22:00 UT. In our preliminary analysis, we find\nno radio source coincident with the refined XRT position (Beardmore\net al., GCN 35780) with 3 sigma upper limits of 75, 54, 69 and 159\nmicroJy/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.\n"
