GCN Circular 33152
Y. Urata and K. Huang, on behalf of a larger collaboration We observed the field of IceCube-221223A (GCN Circ. 33094) using Scuba-2 attached to JCMT. The observations were conducted on 2022/12/24 and 2022/12/29. SCUBA-2 imaged the field centered at RA 23:22:10, Dec +34:42:36 with 40 arcmin diameter. The rms of the stacked map in 850um created using two-night observations is 4.1 mJy. There was no source brighter than the 5-sigma limit.
