We observed the long GRB 260614B detected by SVOM (SVOM Team, GCN 44938) and Fermi-GBM (Fermi GBM Team, GCN 44937) with the Australia Telescope Compact Array (ATCA) 6.4 and 11.5 days post-burst.
No radio source was detected within the SVOM VT localization region (SVOM Team, 44939). At 8 GHz we find 3-sigma upper limits of 27 and 48 microJy/beam, at 6.4 and 11.5 days post-burst 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.
