GCN Circular 13821
A.P. Beardmore (U. Leicester) and S.R. Oates (MSSL-UCL) report on behalf of the Swift-XRT team: Further XRT follow-up observations covering the field of the GBM and IPN-detected burst GRB 120919A (Rau et al. GCN Circ. 13785, Hurley et al. GCN Circ. 13786) have been performed. The data total 15 ks in Photon Counting (PC) mode, collected in three observations from 134 ks to 573 ks after the trigger. The two X-ray sources identified within the IPN error box after the inital XRT observation (Beardmore and Oates, GCN C. 13790) show no evidence for fading. Likewise, none of the additional sources seen in the XRT field, but outside the IPN error box, show evidence for fading, implying we have not detected any X-ray counterpart to this GRB. The 3 sigma detection limit is approximately 2.5e-3 count/s (per 5ks observation), which corresponds to a 0.3-10 keV flux limit of 1.0e-13 erg cm^-2 s^-1 (for a typical GRB spectrum).
