We observed the likely short GRB 241105A (Fermi GBM Collaboration, GCN 38085) with the Australia Telescope Compact Array (ATCA) 4.8 days post-burst on 2024-11-10 (08:30-13:30 UT). No radio source was detected at the location of the optical counterpart (Julakanti et al. GCN 38088, Izzo et al., GCN 38097; SVOM/VT team, GCN 38099; Hu et al., GCN 38106; Siegel et al., GCN 38110; Dichiara et al., GCN 38111; Rastinejad et al., GCN 38113; Tsalapatas et al., GCN 38119) at 5.5 and 9 GHz, with 3-sigma upper limits of 54 and 39 microJy/beam, respectively.
We thank the CSIRO Space and Astronomy staff for supporting these observations.
