Ukwatta (LANL) report on behalf of the Swift Team:\n\nAt 15:16:37 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 160419A (trigger=683383).  Swift did not slew to the\nburst due to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 16.424, -27.343 which is \n   RA(J2000) = 01h 05m 42s\n   Dec(J2000) = -27d 20' 32\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single symmetric \npeak structure with a duration of about 20 sec.  The peak count rate\nwas ~5000 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 01:44 UT on 2016 April 30. There will thus be no XRT or\nUVOT data for this trigger before this time. \n\nBurst Advocate for this burst is C. B. Markwardt (Craig.Markwardt AT nasa.gov). \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.)",
