TITLE: GCN CIRCULAR NUMBER: 37388 SUBJECT: GRB 240825A: ATCA Detection of Radio Counterpart DATE: 24/09/05 02:51:28 GMT FROM: agul8829@uni.sydney.edu.au A. Gulati (USyd), J. K. Leung (UofT/HUJI), G. E. Anderson (Curtin) We observed GRB 240825A (Gupta et al., GCN 37274; Fermi GBM team, GCN 37273) with the the Australia Telescope Compact Array (ATCA) at multiple frequencies starting at 09:00 UTC on 1st September 2024. In our preliminary analysis, we detect a radio counterpart at 5.5 GHz with a flux density of ~0.2 mJy at a position consistent with the X-ray position (Evans et al., GCN 37290), optical position (Gupta et al., GCN 37274; Jiang et al., GCN 37275; Dutton et al., GCN 37276; Odeh et al., GCN 37277; Li et al., GCN 37280; Evans et al., GCN 37290; Leonini et al., GCN 37291; Kuin et al., GCN 37296), and radio position (Laskar et al., GCN 37314, Peña et al., GCN 37322,37353). Further observations are planned. 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.
