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.
