Swift observed the field of IceCube 201222A (GCN Circ. 29120) between 19:24:35 and 2020
21:15:15 on December 22, collecting a total of 2.2 ks of cleaned photon counting (PC)
mode data. The observations used a 2-point tiling pattern.
We found no X-ray sources.
The 3-sigma upper limit in the field was in the range 5-10 x10^-3 ct/sec.
