TITLE: GCN CIRCULAR NUMBER: 7050 SUBJECT: GRB 071109: Swift-XRT possible X-ray counterpart DATE: 07/11/10 03:38:54 GMT FROM: Matteo Perri at ISAC/ASDC M. Perri, G. Stratta (ASDC) and D.N. Burrows (PSU) report on behalf of the Swift-XRT team: Swift-XRT began observing the field of view of the INTEGRAL-detected long burst GRB 071109 (Mereghetti et al., GCN Circ. 7046) at 22:21:50 UT on 2007 November 9, ~1.7 hours after the INTEGRAL trigger. We currently have 4.8 ks of XRT data, in which we detect a faint, uncatalogued X-ray source at a position of RA,Dec(J2000)= 289.974583,+2.046528 degrees, which is equivalent to: RA (J2000 = 19h 19m 53.9s Dec(J2000) = +02d 02' 47.5" with an estimated uncertainty of 9 arcsec (radius, 90% confidence). This is 3.7 arcmin from the INTEGRAL position (Mereghetti et al., GCN Circ. 7046), outside its error circle. We note also that this position is 1.1 arcmin away from the VLA radio source reported in GCN Circ. 7049 (Chandra & Frail). The source has a count rate of (2.5 +/-0.9)e-3 counts s-1. At present we are unable to determine whether the source is fading, however observations are ongoing and further analysis of these XRT data will be reported in a subsequent circular. This circular is an official product of the Swift-XRT team.
