Swift-XRT observations of IceCube 201114A
Abstract
Swift observed the field of IceCube 201114A (GCN Circ. 28887) between 16:50:06 2020 November 14 and 21:26:27 on 2020 November 14, 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 2 X-ray sources, as detailed below. All of these are unknown but with count rate consistent with the previous non-detections. We therefore do not claim any of them as the likely counterpart to IceCube 201114A. The 3-sigma upper limit in the field was in the range 8-10 x 10^-3 ct/sec. The detected sources were: Source no: 1 RA (J2000): 104.52092 [degrees] = 06h 58m 05.02s Dec (J2000): +5.8679 [degrees] = +05d 52' 04.3" Error: +5.5 [arcsec, 90% conf. radius] Count rate (0.3-10 keV): 4.1 (+3.9, -2.4) x 10-3 ct s-1 Flux (0.3-10 keV): 1.8 (+1.7, -1.0) x 10-13 erg cm-2 s-1 Source no: 2 RA (J2000): 104.92274 [degrees] = 06h 59m 41.46s Dec (J2000): +5.7601 [degrees] = +05d 45' 36.4" Error: +6.6 [arcsec, 90% conf. radius] Count rate (0.3-10 keV): 8 (+5, -3) x 10-3 ct s-1 Flux (0.3-10 keV): 3.3 (+2.1, -1.5) x 10-13 erg cm-2 s-1
