TITLE: GCN CIRCULAR NUMBER: 7911 SUBJECT: GRB 080701: Swift-XRT Prompt Analysis DATE: 08/07/01 12:16:48 GMT FROM: Michael Stroh at PSU/Swift M.C. Stroh, C. Pagani (PSU) and P. Evans (U. Leicester) report on behalf of the Swift-XRT team. The XRT began observing the field at 11:00:14.4 UT, 2796.8 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source located at RA, Dec 45.83937, 75.47535 which is equivalent to: RA(J2000) = 03h 03m 21.45s Dec(J2000) = +75d 28' 31.3" with an uncertainty of 3.1 arcseconds (radius, 90% containment). This location is 59 arcseconds from the BAT onboard position, within the BAT error circle. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (1.78e+21 cm-2, Kalberla et al. 2005), with an excess column of 6.3 (+3.88/-3.07) x 10^21 cm-2 (90% confidence). This is an official product of the Swift-XRT team.
