We observed long GRB 231214A (Fermi GBM Collaboration, GCN 35334; R. Brivio et al., GCN 35335) as part of the The Australia Telescope Compact Array (ATCA) "PanRadio GRB" Large Project C3542 (PI: G. Anderson) at 5.5, 9, 16.7, 21.2, 33 and 35 GHz on 2023-12-16 and at 5.5 and 9 GHz on 2023-12-21 UT.
No radio sources were detected near the Swift/XRT enhanced position (J. P. Osborne et al., GCN 35350)in either observation epoch. The 3-sigma upper limits for the 9 GHz observations are 73 and 81 uJy respectively.
We thank the CSIRO Space and Astronomy staff for supporting these observations.
We acknowledge the Gomeroi people as the traditional owners of the Observatory site. The Australia Telescope Compact Array is part of the Australia Telescope National Facility (https://ror.org/05qajvd42) which is funded by the Australian Government for operation as a National Facility managed by CSIRO.
