  "body": "V. D'Elia (ASDC) & L. Izzo (URoma/ICRA) report on behalf of the Swift-XRT team\n\nSwift-XRT has observed the error box of the IPN GRB 141215A (Hurley et  al. GCN 17186) in a series of observations tiled on the sky. The total exposure time is 8.0 ks spread over 2 fields. The observations started ~100 ks after the IPN trigger and cover ~80% of the error box. We detect three sources with S/N>2.5 within the IPN error box, namely (ordered by descending RA):\n\nSource 1\nRA:  178.98953 = 11h 55m 57.49s (J2000) \nDec: -52.90081 = -52d 54' 02.9\" (J2000)\nErr: 3.6 arcsec (radius, 90% confidence)\nExposure time: 3.3 ks.\n\nSource 2\nRA:  178.95882 = 11h 55m 50.12s (J2000) \nDec: -52.82640 = -52d 49' 35.1\" (J2000)\nErr: 4.3 arcsec (radius, 90% confidence)\nExposure time: 3.4 ks.\n\nSource 3\nRA:  178.80790 = 11h 55m 13.90s (J2000) \nDec: -52.84520 = -52d 50' 42.7\" (J2000)\nErr: 5.1 arcsec (radius, 90% confidence)\nExposure time: 3.4 ks.\n\n\nSource #1 has a 2MASS counterpart and it is fairly bright (5E-2 cts/s) for being an X-ray afterglow at more than 30 hours from the trigger. Thus, the current candidates are #2 and #3. We cannot assess variability at this time, so a secure identification of the afterglow is not possible. We caution that the XRT observations cover just 80% of the IPN error box. A further Swift-XRT follow-up is planned. \n\nDetails on the present analysis can be found at:\n\nhttp://www.swift.ac.uk/xrt_products/TILED_GRB00035/\n\n\nThis is an official product of the Swift-XRT team.",
