  "body": "Dirk Grupe (Swift MOC, PSU)  reports on behalf of the \nSwift team:\n\nWe report on the Swift XRT observations of the field of the\nFermi GBM detected GRB 140105A (Xiong & Connaughton GCN Circ. \n15688). We followed three of the four afterglow candidates \nreported by Singer et al. (GCN circular 15686). We did not find \nan X-ray source in any of these observations. Below is a summary \nof the XRT observations:\n\niPTF14ai: target ID 20338, T-exp=3939s, \n          Tstart = 2014-01-05 19:46\n          3sigma ul = 1.5e-3 counts/s\n\t  \niPTF14ae:  target ID 20339, T-exp=3962s\n          T-start = 2014-01-05 23:01\n          3sigma ul = 1.53-3 counts/s\n          Note that the bright source in the XRT image\n\t  is the Seyfert 1 galaxy SBS 1343+537.\n\t  \niPFT14x:  target ID 20340, T-exp=3077s\n          T-start = 2014-01-06 08:56\n          3sigma ul = 2.8e-3 counts/s\n\t  \n\t  \nNote that Swift was not able to observe the field of the forth\nsource, iPTF14ac, because the star tracker did not lock onto the\ntarget and caused Swift to go into a safehold. \n\nThis report is an official product of the Swift team.",
