Tohuvavohu (U Toronto) report on behalf of the Neil Gehrels Swift\nObservatory Team:\n\nAt 10:42:10 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 210430A (trigger= 1046014).  Swift did not slew immediately\ndue to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 57.178, +45.074 which is \n   RA(J2000) = 03h 48m 43s\n   Dec(J2000) = +45d 03' 31\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  With the currently available data from\n~T-50 s to ~T+30 s, the BAT light curve showed a single-peaked\nstructure with a duration of about 10 sec.  The peak count rate\nwas ~500 counts/sec (15-350 keV), at ~2 sec after the trigger. \n\nThe BAT position is sun-constrained for Swift until July 8 2021,\nthere will be no XRT or UVOT followup before this time. \n\nBurst Advocate for this burst is B. Sbarufatti (bxs60 AT 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/)",
