GRB 231110A: Swift-XRT afterglow detection
Abstract
Swift-XRT has performed follow-up observations of the Swift-BAT-detected burst GRB 231110A, collecting 10 ks of Photon Counting (PC) mode data between T0+8.9 ks and T0+61.1 ks. Four uncatalogued X-ray sources are detected consistent with being within 296 arcsec of the Swift-BAT position, of which one ("Source 2") is believed to be the afterglow. The position of this source is RA, Dec=356.2752, +82.6447 which is equivalent to: RA (J2000): 23:45:6.05 Dec(J2000): +82:38:40.9 with an uncertainty of 5.1 arcsec (radius, 90% confidence). This position is 85 arcsec from the Swift-BAT position. There is evidence that the source may be fading, however we cannot constrain the decay at the current time The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/01195733. The results of the full analysis of the XRT observations are available at https://www.swift.ac.uk/ToO_GRBs/01195733. This circular is an official product of the Swift-XRT team.
