TITLE: GCN CIRCULAR NUMBER: 7565 SUBJECT: GRB 080405: Swift-XRT position DATE: 08/04/07 10:04:46 GMT FROM: Boris Sbarufatti at INAF-IASF-Pa V. La Parola, B. Sbarufatti, V. Mangano (INAF-IASF PA) and D.N. Burrows (PSU) report on behalf of the Swift XRT team. The XRT began observing GRB 080405 (Cummings et al., GCN 7564) on 2008-04-07 at 04:25:49, ~43 hours after the trigger. The observation is in PC mode and consists of 1.5 ksec split over two orbits. A single uncatalogued source is detected in the whole XRT field of view, with coordinates: RA = 10:50:23.64 (162.59850) Dec = -04:17:18.5 (-4.288476) with an uncertainty of 7.1 arcsec (radius, 90% containment). This position lies 2.3 arcmin from the BAT position (slightly outside the BAT error circle). The source has a count rate of 1.029E-02 ± 2.9E-03 c/s, corresponding to an unabsorbed flux of 4.63e-13 ergs/s/cm-2 (assuming a standard powerlaw spectrum with index 2.0 and a Galactic line of sight absorbing column of 3.8e20 cm-2). With these data we cannot assess if the source is decaying. This circular is an official product of the Swift-XRT team.
