TITLE: GCN CIRCULAR NUMBER: 43542 SUBJECT: GRB 260127B: Swift ToO observations DATE: 26/01/28 15:34:04 GMT FROM: Phil Evans at U of Leicester <pae9@star.le.ac.uk> P. A. Evans (U. Leicester) reports on behalf of the Swift team: Swift has initiated a ToO observation of the Fermi/GBM-detected event GRB 260127B. Automated analysis of the XRT data will be presented online at https://www.swift.ac.uk/ToO_GRBs/00021900 Any uncatalogued X-ray sources detected in this analysis will be reported on this website and via GCN COUNTERPART notices. These are not necessarily related to the Fermi/GBM event. Any X-ray source considered to be a probable afterglow candidate will be reported via a GCN Circular after manual consideration. Details of the XRT automated analysis methods are detailed in Evans et al. (2007, A&A, 469, 379; 2009, MNRAS, 397, 1177 and 2014, ApJS, 210, 8).
