Sbarufatti (PSU) report on behalf of\nthe Neil Gehrels Swift Observatory Team:\n\nAt 07:07:48 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 210527A (trigger=1051453).  Swift did not slew immediately \ndue to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 172.355, +31.618 which is \n   RA(J2000) = 11h 29m 25s\n   Dec(J2000) = +31d 37' 06\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is normal for an image trigger, the BAT \nlight curve does not show any significant structure. \n\nDue to an observing constraint, Swift will not slew until T0+49.6\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is S. Laha (sib.laha 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/)",
