TITLE: GCN CIRCULAR NUMBER: 9617 SUBJECT: Possible GRB090705: Swift-XRT observations DATE: 09/07/05 13:25:13 GMT FROM: Valerio D'Elia at INAF-OAR V. D'Elia, M. Perri (ASDC), T.N. Ukwatta (GSFC/GWU) report on behalf of the Swift-XRT team: We analyzed the first 2.9 ks of the XRT data for the possible GRB 090705 (Ukwatta et al., GCN Circ. 9615). Data are in Photon Counting (PC) mode and start ~6 minutes after the BAT trigger. No source is detected within or near to the BAT error circle. The 3-sigma upper limit on the count rate is 0.005 count s-1, corresponding to an approximate observed 0.3-10 keV flux of 2.5x10-13 erg cm-2 s-1 (using a standard counts to flux conversion factor). This circular is an official product of the Swift-XRT team. ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
