Berger (Harvard University), R. Chornock\n(UC Berkeley), W. Fong (Northwestern University), R. Margutti (UC\nBerkeley), and P. Schady (University of Bath) report on behalf of a larger\ncollaboration:\n\n\"We observed GRB 240809A (Evans et al., GCN 37110) with the Atacama Large\nMillimeter/Submillimeter Array (ALMA) at 97.5 GHz over two epochs,\nbeginning on 2024 August 09 19:30 UT and 2024 August 10 23:28 UT, at 11 h\nand 39 h after the burst, respectively. Preliminary analysis reveals a\nfading mm source, with flux density of ~ 0.1 mJy in the first epoch, which\nwe identify as the radio counterpart of GRB 240809A. Further observations\nare planned.\n\nWe thank the JAO staff, AoD, P2G, and the entire ALMA team for their help\nwith these observations.\"\n",
