TITLE: GCN CIRCULAR NUMBER: 14288 SUBJECT: Swift XRT observations of GRB 130310A DATE: 13/03/12 03:12:58 GMT FROM: Boris Sbarufatti at INAF-OAB/IASFPA B. Sbarufatti (INAF-OAB/PSU), D. N. Burrows (PSU), J. L. Racusin (NASA/GSFC), C. J. Mountford (U Leicester), N. Gehrels (NASA/GSFC) report on behalf of the Swift team: Swift performed 3 pointings of 1.5 ks each to cover the IPN error box for GRB 130310A (Golenetskii et al., GCN #14284). A single, uncatalogued source is detected at coordinates: RA/Dec (J2000) = 09 27 36.35 -17 06 16.1 RA/Dec (J2000) = 141.901 -17.1044 Error radius (arcsec) = 3.6 (90% confidence level) The source is inside the IPN error box, and 0.44 degrees from the Fermi LAT position (Guiriec et al., GCN #14282), just inside the LAT error circle. The countrate is 7.60E-03 +/- 2.5E-03 c/sec At present is not possible to tell if the source is fading. This circular is an official product of the Swift-XRT team.
