TITLE: GCN CIRCULAR NUMBER: 16816 SUBJECT: GRB 140909A: Confirmation of the Swift-XRT afterglow DATE: 14/09/12 10:36:45 GMT FROM: Claudio Pagani at U of Leicester C. Pagani (U. Leicester) and E. Sonbas (Adiyaman U.) report on behalf of the Swift team: A second epoch of XRT data was collected on the field of the Swift/BAT ground detected GRB 140909A (Palmer, GCN Circ. 16808), from 148 ks to 252 ks after the Swift/BAT trigger. The X-ray source reported in GCN Circ. 16811, Pagani et al., at a mean count rate of 6.9e-03 ct/sec, is now no longer detected, having faded below a 3-sigma upper limit of 2.3 x 10^-3 count s^-1 (0.3-10 keV). We therefore confirm that this is the X-ray afterglow of GRB 140909A This circular is an official product of the Swift-XRT team.
