GCN 30351) with the Atacama Large\nMillimeter/Submillimeter Array (ALMA) at 97.5 GHz and 343.5 GHz beginning\non 2021 July 03 21:05:52 UT (26.0 h after the burst). ALMA observations of\nthis burst were delayed due to uninterruptible scheduled Cycle 8 software\nvalidation at the Observatory.\n\nPreliminary analysis reveals a mm source with flux density of ~ 0.1 mJy at\n97.5 GHz and position:\n\nRA (J2000) = 11:14:18.807\nDec (J2000) = -36:44:49.25\n\nwith uncertainty ~ 0.03\" in each coordinate, consistent with the X-ray\nposition (D'Elia et al., GCN 30358) and optical position (Lien et al., GCN\n30351; Kuin et al., GCN 30356). The spectrum appears strongly self-absorbed\nin the mm-band. Further observations are planned.\n\nWe thank the JAO staff, AoD, P2G, and the entire ALMA team for their help\nwith these observations.\"",
