GCN Circular 7247
R.L.C. Starling, P.A. Evans, P.T. O'Brien (U. Leicester), C. Guidorzi (U. Bicocca/INAF-OAB) and M. Stamatikos (GSFC/ORAU) report on behalf of the Swift XRT team: Swift XRT re-observed the field of possible ground-detected GRB 080130 (Copete et al., GCN 7242), approximately 34 hours after the burst. In 4.98ks of Photon Counting (PC) mode data starting 2008-01-31:16:01 and ending 2008-01-31:20:51 we still detect an X-ray source inside the BATSS error circle at the 3-sigma level (Starling and Stamatikos, GCN 7243). By combining both XRT datasets for this field totalling ~7 ks we refine the source position to RA,Dec=261.61484,-53.18742 deg, equivalent to: RA (J2000)= 17h 26m 27.56s Dec(J2000)= -53d 11' 14.7" with an uncertainty of 5 arsec (radius, 90% confidence). This is 6.2 arcsec from the previously reported XRT position, and 2.2 arcmin from the BATSS position. The count rate of the source in this second observation is 0.004+/-0.001 counts/s. Compared to the earlier measured count rate of 0.010+/-0.002 counts/s we can confirm that the source has faded. We conclude that GRB 080130 was a real GRB, and that the source reported here is its X-ray afterglow. This is an official product of the Swift XRT team.
