GCN Circular 6119
G. Stratta, M. Perri, M. L. Conciatore (ASDC), D. N. Burrows (PSU) and G. Sato (GSFC/ISAS) report on behalf of the Swift/XRT team: The field of the short hard BAT GRB 070209 (Sato et al., GCN Circ. 6086) has been re-observed by Swift in two epochs at about T+5 days and T+9 days after the BAT trigger. The XRT exposures in Photon Counting mode were 19.4 ks and 22.8 ks, respectively. We found no X-ray sources within the BAT refined error circle (Sakamoto et al., GCN Circ. 6087). The three X-ray sources reported by Stratta et al. (GCN Circ. 6095) close to the BAT error circle are still detected at the same count rate level of the first follow-up observation. We conclude that none of these sources is the afterglow of the burst. The three sigma upper limit on the 0.7-10 keV count rate during the first observation within the BAT error circle was about 7e-4 cts/s. Assuming an absorbed power-law spectral model with Galactic NH (2.3e20 cm-2) and a photon index of 2 this corresponds to an observed 0.7-10 keV flux of about 3e-14 erg cm-2 s-1. This circular is an official product of the Swift XRT Team.
