Page (U Leicester) report on behalf\nof the Swift Team:\n\nAt 11:10:53 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 160220B (trigger=674734). Swift did not slew immediately\ndue to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 259.854, -18.123 which is \n   RA(J2000) = 17h 19m 25s\n   Dec(J2000) = -18d 07' 22\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a multi-peaked\nstructure with a duration of about 30 sec.  The peak count rate\nwas ~6000 counts/sec (15-350 keV), at ~6 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until T0+46.5\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is J. R. Cummings (jayc AT milkyway.gsfc.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.)",
