TITLE: GCN CIRCULAR NUMBER: 7199 SUBJECT: GRB 080120: Swift-XRT refined analysis DATE: 08/01/21 14:14:40 GMT FROM: Boris Sbarufatti at INAF-IASF-Pa B. Sbarufatti, V. Mangano (INAF-IASF PA) report on behalf of the Swift-XRT team: We have analyzed the 3.9 ks of data of the ToO observation of GRB 080120, started on Jan 20 at 19:47 UT. The refined position of the X-ray source is Ra (J2000): 15h 01m 03.14s Dec (J2000): -10d 52' 30.7" with an uncertainty of 3.7 arcsec (radius, 90% confidence). This is 1.1 arcsec away from the first XRT position given in Sbarufatti & Mangano (GCN Circ. 7195), 47.2 arcsec from the initial INTEGRAL position of Mereghetti et al. (GCN Circ. 7194), and 2.2 arcsec from the optical counterparts reported by Kruehler et al. (GCN Circ, 7197) and by Schady & Sbarufatti (GCN Circ. 7198). The light curve shows an initial flare between 8 and 9 ks from the trigger, followed by a very steep decay (slope 2.9 +/- 0.4). At this decay rate the source will be at a level of 3E-4 counts/s today at 17:30 UT. The average spectrum can be modeled by an absorbed powerlaw with photon index 2.5 +/- 0.3 with a column density of (1.5 +/- 0.6)E21 cm^-2, sligthly in excess with respect to the Galactic value (7.7E20 cm^-2). The observed (unabsorbed) 0.3-10 keV flux is 4.7E-12 (8.2E-12) ergs cm^-2 s^-1. This circular is an official product of the Swift-XRT team.
