  "body": "V. D'Elia (ASDC) and L. Izzo (URoma/ICRA) report on behalf of the  \nSwift/XRT Team:\n\nSwift began a series of observations, tiled on the sky, of the  \nFermi/GBM and /LAT GRB 140523A (von Kienlin et al. GCN 16321, Vianello  \net al. GCB 16322).\n\nObservations cover four contiguous fields, starting on May 23 at 18:34  \nUT, i.e., 15.5 h after the GBM detection. Each field was observed for  \nabout 2 ks.\n\nA possible XRT candidate counterpart for the GBM/LAT source is  \ndetected at Ra, Dec 133.111250, +24.957111, which is equivalent to:\n\nRa(J2000)   =    08h 52m 26.7s\nDec(J2000) =  +24d 57' 25.6\"\n\nwith an uncertainty of 6.4\" (S/N~3). This location is 10.3 arcmins  \nfrom the LAT position, within the LAT error box.\n\nNo statement about fading can be made at this stage.\n\nWe note the presence of a SDSS galaxy (r=22.27) a few arcsec SW to the  \ncenter of the XRT detection, consistent with the X-ray position.",
