GCN Circular 10809
L. Vetere and M. H. Siegel (PSU) report on behalf of the Swift-XRT team: We have now collected 5.7 ks of Swift-XRT Photon Counting mode data on the GRB 100526B (Siegel et al. GCN Circ. 10799), from 3289 s to 34.8 ks after the BAT trigger. The source reported by Kennea et al. (GCN Circ. 10802) is now only marginally detected, with a count rate of 1.5x10^-3 count s^-1 (corresponding to an observed flux of 7.1x10^-14 erg cm^-2 s^-1). With this fading, we can confirm that this source is the X-ray afterglow of GRB 100526B. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00423184. This circular is an official product of the Swift-XRT team.
