TITLE: GCN CIRCULAR NUMBER: 15694 SUBJECT: GRB 140105A: Swift XRT observations DATE: 14/01/06 22:05:49 GMT FROM: Dirk Grupe at PSU/Swift-XRT Dirk Grupe (Swift MOC, PSU) reports on behalf of the Swift team: We report on the Swift XRT observations of the field of the Fermi GBM detected GRB 140105A (Xiong & Connaughton GCN Circ. 15688). We followed three of the four afterglow candidates reported by Singer et al. (GCN circular 15686). We did not find an X-ray source in any of these observations. Below is a summary of the XRT observations: iPTF14ai: target ID 20338, T-exp=3939s, Tstart = 2014-01-05 19:46 3sigma ul = 1.5e-3 counts/s iPTF14ae: target ID 20339, T-exp=3962s T-start = 2014-01-05 23:01 3sigma ul = 1.53-3 counts/s Note that the bright source in the XRT image is the Seyfert 1 galaxy SBS 1343+537. iPFT14x: target ID 20340, T-exp=3077s T-start = 2014-01-06 08:56 3sigma ul = 2.8e-3 counts/s Note that Swift was not able to observe the field of the forth source, iPTF14ac, because the star tracker did not lock onto the target and caused Swift to go into a safehold. This report is an official product of the Swift team.
