The Australia Telescope Compact Array (ATCA) performed observations
of the long GRB 240712A detected by Swift-BAT (Salvaggio et al., GCN 36851),
at 5.5, 9, 16.7 and 21.2 GHz as part of the Large ATCA "PanRadio GRB"
follow-up programme C3542 (PI. Anderson). ATCA start observing on
2024-07-12 at 4:08 UT (~2 hours post-burst) and continued to observe
until 9:21 UT on 2024-07-12. In our preliminary analysis, we find
no radio source coincident with the Swift XRT uncataloged source
(Salvaggio et al., GCN 36851) with 3 sigma upper limits of
72, 63, 192 and 717 microJy/beam at 5.5, 9.0, 16.7 and 21.2 GHz, 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.
