TITLE: GCN CIRCULAR NUMBER: 35358 SUBJECT: ATCA observations of GRB 231210B DATE: 23/12/15 16:40:25 GMT FROM: Lauren Rhodes at Oxford <lauren.rhodes@physics.ox.ac.uk> L. Rhodes (Oxford), G. E. Anderson (Curtin), A. J. van der Horst (GWU), J. K. Leung (UofT/HUJI), O. Sharan Salafia (INAF), S. D. Ryder (Macquarie), A. Gulati (USyd), S. Chastain (UNM) on behalf of the PanRadio GRB collaboration We observed short GRB 231210B (Page et al., GCN 35314) starting at 2023-12-14 10:56UT for 9 hours with the Australia Telescope Compact Array (ATCA), as part of the "PanRadio GRB" Large ATCA follow-up programme C3542 (PI. Anderson). We do not detect any clear radio counterpart. The rms noise in our observations is 17 and 12 uJy/beam at 5.5 and 9GHz, respectively. At a redshift of 3.13 (Saccardi et al GCN 35317), our measurements correspond to 3-sigma upper limits of 6.6e30 and 4.7e30 erg/s/Hz at 5.5 and 9GHz, respectively (assuming H0 = 70km/s/Mpc and OmegaM = 0.3) 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.
