Kuwata and J.\nShimoda\n\nWe observed the field of GRB 221009A (Dichiara GCN 32632) with ALMAand ACA\nat 97.5, 145, and 203 GHz.  The afterglow is significantly detected at all\nbands, and the flux at 97.5 GHz was ~7 mJy at 4.3 days after the burst.\nTogether with the SMA measurements at the\nsimilar epoch (Rhodes et al. GCN 32707), the spectrum seems to be flat\naround the mm/submm band.\n\nWe thank ALMA staff for rapidly scheduling and supporting these\nobservations.",
