  "body": "P. A. Evans (U Leicester), J. A. Kennea (PSU),\nK. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of\nthe Neil Gehrels Swift Observatory Team:\n\nBAT has detected GRB 180205A (trigger #808625), leading to a slew\nand follow-up observations by Swift.  However, due to missing \ntelemetry packets, no further BAT information is available at \nthis time. \n\nThe XRT began observing the field at 04:28:23.6 UT. XRT found \na bright, uncatalogued X-ray source\nlocated at RA, Dec 126.8206, 11.5419 which is equivalent to:\n   RA(J2000)  = +08h 27m 16.94s\n   Dec(J2000) = +11d 32' 30.8\"\nwith an uncertainty of 5.6 arcseconds (radius, 90% containment). No\nevent data are yet available to determine the column density using\nX-ray spectroscopy. \n\nThe initial flux in the 2.5 s image was 9.50e-10 erg cm^-2 s^-1 (0.2-10\nkeV). \n\nUVOT took a finding chart exposure of 150 seconds with the White filter\nat 04:28:30.79 UT. There is a candidate afterglow in\nthe rapidly available 2.7'x2.7' sub-image at\n  RA(J2000)  =\t08:27:16.73 = 126.81970\n  DEC(J2000) = +11:32:30.7  =  11.54185\nwith a 90%-confidence error radius of about 0.61 arc sec. This position is 3.2\narc sec. from the center of the XRT error circle. The estimated magnitude is\n15.65 with a 1-sigma error of about  0.14. No correction has been made for the\nexpected extinction corresponding to E(B-V) of 0.03. \n\nBurst Advocate for this burst is P. A. Evans (pae9 AT star.le.ac.uk). \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.)",
