TITLE: GCN CIRCULAR NUMBER: 6710 SUBJECT: GRB 070805: Swift XRT initial analysis. DATE: 07/08/06 03:47:39 GMT FROM: Valentina La Parola at INAF-IASPA V. La Parola, J. Kennea, E. Troja, V. Mangano, B. Sbarufatti on behalf of the Swift team. We have analysed the first 2.3 ks of the XRT observation of GRB070805 (Parsons et al., GCN 6708). Due to Earth limb constraint the XRT began observing the GRB location 33 min after the trigger, at 20:28:48 UT. No sources are visible in this first orbit of data, with an upper limit to the unabsorbed flux of 2.4e-13 erg/s/cm2. We are waiting for more data for further analysis.
