TITLE: GCN CIRCULAR NUMBER: 37508 SUBJECT: GRB 240914A: Swift-XRT observations DATE: 24/09/14 16:53:41 GMT FROM: Phil Evans at U of Leicester pae9@star.le.ac.uk
S. Dichiara (PSU), K.L. Page (U. Leicester), A.P. Beardmore (U. Leicester), P. D'Avanzo (INAF-OAB), M.G. Bernardini (INAF-OAB), E. Ambrosi (INAF-IASFPA) , J.A. Kennea (PSU), D.N. Burrows (PSU) and P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
Swift-XRT has performed follow-up observations of the SVOM/ECLAIRs-detected burst GRB 240914A, collecting 1.9 ks of Photon Counting (PC) mode data between T0+36.3 ks and T0+42.4 ks.
No uncatalogued X-ray sources have been detected. The 3-sigma upper limit in the field ranges from ~0.005 to ~0.006 ct s^-1, corresponding to a 0.3-10 keV observed flux of 1.9e-13 to 2.3e-13 erg cm^-2 s^-1 (assuming a typical GRB spectrum).
Three previously-catalogued X-ray sources have been detected, however their status as catalogued objects makes them unlikely to be the afterglow.
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/00021716.
