Siegel (PSU) report on behalf of the\nNeil Gehrels Swift Observatory Team:\n\nAt 04:34:15 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 190427A (trigger=900730).  Swift's slew will be delayed\ndue to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 280.213, +40.322 which is \n   RA(J2000) = 18h 40m 51s\n   Dec(J2000) = +40d 19' 20\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single short\nstructure with a duration of about 0.5 sec.  The peak count rate\nwas ~6000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until T0+43.4\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is A. Tohuvavohu (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/)",
