TITLE: GCN CIRCULAR NUMBER: 38096 SUBJECT: GRB 241104A: Swift-XRT observations DATE: 24/11/06 08:51:15 GMT FROM: Phil Evans at U of Leicester <pae9@star.le.ac.uk> S. Dichiara (PSU), J.A. Kennea (PSU), D.N. Burrows (PSU), K.L. Page (U. Leicester), A.P. Beardmore (U. Leicester), M. Capalbi (INAF-IASFPA), M. Perri (SSDC & INAF-OAR), V. D'Elia (SSDC & INAF-OAR) and P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: Swift-XRT has performed follow-up observations of the Fermi/GBM-detected burst GRB 241104A, using the localisation by SVOM/ECLAIRs (Schanne et al., GCN 38078), collecting 2.9 ks of Photon Counting (PC) mode data between T0+98.0 ks and T0+105.0 ks. No X-ray sources have been detected consistent with being within 256 arcsec of the SVOM/ECLAIRs position. The 3-sigma upper limit in the field is 0.005 ct s^-1, corresponding to a 0.3-10 keV observed flux of 2.1e-13 erg cm^-2 s^-1 (assuming a typical GRB spectrum). Three uncatalogued sources were detected too far from the GRB position to be likely afterglow candidates. These sources are also inconsistent with the X-ray localisation by EP/WXT (Zhou et al., GCN 38081). The results of the XRT-team automatic analysis of the XRT observations, including a position-specific upper limit calculator, are available at https://www.swift.ac.uk/ToO_GRBs/00021727.
