Siegel (PSU)\nreport on behalf of the Swift Team:\n\nAt 21:33:46 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 170419B (trigger=748947).  Swift did not slew due to Sun constraint. \nThe BAT on-board calculated location is \nRA, Dec 60.498, -15.143, which is \n   RA(J2000)  =  04h 01m 59s\n   Dec(J2000) = -15d 08' 32\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows a single \nwith a duration of about 10 sec.  The peak count rate\nwas ~3000 counts/sec (15-350 keV), at ~3 sec after the trigger. \n\nDue to a Sun observing constraint, Swift cannot slew to the BAT\nposition until 05:29 UT on 2017 June 19. There will thus be no XRT or\nUVOT data for this trigger before this time. \n\nBurst Advocate for this burst is A. Cholden-Brown (aaronb AT swift.psu.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/too.html.)",
