TITLE: GCN CIRCULAR NUMBER: 32262 SUBJECT: GRB 220611A: X-ray afterglow Chandra sub-arcsecond localization DATE: 22/06/24 18:10:44 GMT FROM: Daniele B Malesani at Radboud U A. J. Levan (Radboud Univ.), D. B. Malesani (Radboud Univ. and DAWN/NBI), B. P. Gompertz (Birmingham) report on behalf of a larger collaboration: The Chandra X-ray observatory imaged the X-ray afterglow of GRB 220611A (Cenko et al., GCN 32191). Observations started on 2022 Jun 23.92 UT (12.15 days after the GRB), using the ACIS-S instrument, for a total exposure time of 15 ks. We detect a single object consistent with the Swift X-ray position (Goad et al., GCN 32192), with a total of ~30 source counts. Its coordinates are (J2000): RA = 04:26:03.57 Dec = -37:15:35.1 with an uncertainty of ~0.5". This position is consistent with the optical and near-infrared source reported by Gemini-S (O’Connor et al., GCN 32203, 32217; Rastinejad et al., GCN 32208) and VLT (Malesani et al., GCN 32222), as well as with the source seen in archival images from the Legacy Survey. This detection thus cements the nature of this object as the mutli-wavelength afterglow of GRB 220611A. We thank the Chandra director, Pat Slane, for awarding discretionary time to this project, and the observatory staff for rapidly planning and scheduling these observations.
