GCN Circular 30341
Antonino D'A�� (INAF-IASFPA) & Aaron Tohuvavohu (Uni. Toronto) report on behalf of the Swift-XRT team: Swift-XRT has performed further follow-up observations of the Fermi/GBM (von Kienlin GCN 30340) and Swift/BAT-GUANO detected burst GRB 210626A (Tohuvavohu et al., GCN Circ. 30325), collecting 7.9 ks of Photon Counting (PC) mode data between T0+29.7 ks and T0+143 ks. The X-ray source detected in the first 1.4 ks of data as possible GRB afterglow candidate (Perri et al. GCN 30329) has faded more than 3 sigma in the latest observation, and it is thus confirmed as the X-ray afterglow of the burst. The results of the full analysis of the XRT observations are available at https://www.swift.ac.uk/xrt_curves/00021453/. This circular is an official product of the Swift-XRT team.
