  "body": "T. Laskar, C. Peña (Utah), G. Schroeder (Northwestern), and K. D. Alexander\n(Arizona) report on behalf of a larger collaboration:\n\n\"We observed GRB 240218A (Page et al., GCN 35742; Veres et al., GCN 35755;\nSvinkin et al., GCN 35758) with the Atacama Large Millimeter/Submillimeter\nArray (ALMA) at 97.5 GHz beginning on 2024 March 02 02:46:33 UT (13.0 d\nafter the burst). ALMA observations of this burst were delayed due to\nALMA's annual February shutdown.\n\nPreliminary analysis reveals a mm source with flux density of ~ 0.1 mJy at\n97.5 GHz and position:\n\nRA (J2000) = 10:47:11.5\nDec (J2000) = 1:16:36.0\n\nwith uncertainty ~ 0.3\" in each coordinate, consistent with the X-ray\nposition (Evans et al. GCN 35748) and radio position (Schroeder et al., GCN\n35794).\n\nWe thank the JAO staff, AoD, P2G, and the entire ALMA team for their help\nwith these observations.\"\n"
