Leicester) report: Swift observed the field of IceCube 200911A (GCN Circ. 28411) between 16:38:01 2020 September 9 and 19:38:41 on 2020 September 9, collecting a total of 3.7 ks of cleaned photon counting (PC) mode data. The observations used a 4-point tiling pattern with a radius of ~0.3 degrees. We found no X-ray sources beyond artifacts caused by bright Earth limb contamination. The 3-sigma upper limit in the field was in the range 5-8 x10^-3 ct/sec.
