  "body": "N. J. Klingler (GSFC/UMBC/CRESSTII), S. Dichiara (PSU),\nR. Gupta (NASA GSFC), N. P. M. Kuin (UCL-MSSL), A. Mei (INAF-OAB),\nC. Salvaggio (INAF-OAB) and T. Sbarrato (INAF-OAB) report on behalf of\nthe Neil Gehrels Swift Observatory Team:\n\nAt 21:54:40.55 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 251014D (trigger=1404126).  Swift slewed immediately to the burst.\nThe BAT on-board calculated location is \nRA, Dec 323.918, -41.839 which is \n   RA(J2000) = 21h 35m 40s\n   Dec(J2000) = -41d 50' 20\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty). The BAT light curve is not available because of a \ntelemetry gap; however, the rate significance of 8.71 indicates that the \nevent is likely real.\n\nThe XRT began observing the field at 21:57:16.2 UT, 155.7 seconds\nafter the BAT trigger. No source was detected in the 2.5-s promptly\navailable image. We are waiting for the full dataset to detect and\nlocalise the XRT counterpart.\n\nThe UVOT source list for the first white image shows no detection of a\nnew source. Typical upper limits are 17th magnitude. Further details\nwill become available when the full data are downloaded.\n\nBurst Advocate for this burst is N. J. Klingler (noelklin AT umbc.edu).\nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/)\n\n",
