We observed GRB 241006A (Gupta et al., GCN 37722) as part of the Australia Telescope Compact Array (ATCA) "PanRadio GRB" Large Project C3542 (PI: G. Anderson) at 5.5 and 9 GHz, 5.2 hours post-merger on 2024-10-07 (03:03-14:32 UT) and 2.25 days post-merger on 2024-10-09 (04:30-08:30 UT).
No radio sources were detected near the Swift/XRT enhanced position (A.P. Beardmore et al., GCN 37724) in either observation epoch. The 3-sigma upper limits for the 9 GHz observations are 27 and 39 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.
