Tohuvavohu (PSU) report\non behalf of the Swift Team:\n\nAt 23:10:32 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 171103A (trigger=785850).  Swift did not slew due to an \nobserving constraint. \nThe BAT on-board calculated location is \nRA, Dec 249.536, -10.215 which is \n   RA(J2000) = 16h 38m 09s\n   Dec(J2000) = -10d 12' 53\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single-peaked\nstructure with a duration of less than 1 sec.  The peak count rate\nwas ~20000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nDue to a Sun observing constraint, Swift cannot slew to the BAT\nposition until 11:32 UT on 2018 January 15. There will thus be no XRT\nor UVOT data for this trigger before this time. \n\nBurst Advocate for this burst is T. N. Ukwatta (tilan.ukwatta AT gmail.com). \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.)",
