GRB 210618A: Swift-XRT afterglow detection
Abstract
Swift-XRT has conducted further observations of the field of the Swift-BAT-detected burst GRB 210618A (Bernardini et al. GCN Circ. 30250). The observations now extend from T0+3.7 ks to T0+424.9 ks. Of the sources reported by Osborne et al. (GCN Circ. 30252), "Source 2" is believed to be the afterglow. The position of this source is RA, Dec=235.7698, +46.0691 which is equivalent to: RA (J2000): 15:43:04.75 Dec(J2000): +46:04:08.6 with an uncertainty of 9.3 arcsec (radius, 90% confidence). This position is 2.6 arcmin from the Swift-BAT position. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/01056426. The results of the full analysis of the XRT observations are available at https://www.swift.ac.uk/ToO_GRBs/01056426. This circular is an official product of the Swift-XRT team.
