Mei (INAF-OAB) report on behalf of the Swift-XRT team:\n\nSwift-XRT has conducted further observations of the field of the SVOM/ECLAIRs-detected burst GRB 251116C (Pillas et al., GCN 42703). The observations now extend from T0+10 ks to T0+452 ks and have a total exposure time of 6.1 ks. \n\nThe previously-reported \"Source 1\" (Evans et al., GCN 42721), is now found to be fading with ~3-sigma significance, and is therefore likely the GRB afterglow. \n\nThe results of the XRT-team automatic analysis of the source are available at https://www.swift.ac.uk/SVOM/team/SVOM_FIELD00051/Source1.php. The results of the full analysis of the XRT observations are available at https://www.swift.ac.uk/SVOM/SVOM_FIELD00051/.\n\nThis circular is an official product of the Swift-XRT team.",
