Page (U Leicester), D. M. Palmer (LANL) and M. H. Siegel (PSU)\nreport on behalf of the Swift Team:\n\nAt 17:20:10 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 161214B (trigger=726885).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 3.850, +7.342 which is \n   RA(J2000) = 00h 15m 24s\n   Dec(J2000) = +07d 20' 31\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single FRED-shaped\nstructure with a duration of about 20 sec.  The peak count rate\nwas ~2900 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nThe XRT began observing the field at 17:21:25.5 UT, 74.9 seconds after\nthe BAT trigger. Using promptly downlinked data we find a bright,\nuncatalogued X-ray source located at RA, Dec 3.85151, 7.35291 which is\nequivalent to:\n   RA(J2000)  = 00h 15m 24.36s\n   Dec(J2000) = +07d 21' 10.5\"\nwith an uncertainty of 4.2 arcseconds (radius, 90% containment). This\nlocation is 39 arcseconds from the BAT onboard position, within the BAT\nerror circle. This position may be improved as more data are received;\nthe latest position is available at http://www.swift.ac.uk/sper.  We\ncannot determine whether the source is fading at the present time. No\nspectrum from the promptly downlinked event data is yet available to\ndetermine the column density. \n\nThe initial flux in the 2.5 s image was 1.29e-09 erg cm^-2 s^-1 (0.2-10\nkeV). \n\nUVOT data are unavailable at this time. \n\nBurst Advocate for this burst is P. D'Avanzo (paolo.davanzo AT brera.inaf.it). \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/too.html.)",
