  "body": "\nA. Tohuvavohu (U Toronto), J. A. Kennea (PSU),\nK. L. Page (U Leicester), D. M. Palmer (LANL), M. H. Siegel (PSU) and\nM. A. Williams (PSU) report on behalf of the Neil Gehrels Swift\nObservatory Team:\n\nAt 17:09:19 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 230506C (trigger=1167288).  Swift did not immediately slew\ndue to an observing constraint.  The BAT on-board calculated location is \nRA, Dec 134.373, +45.126 which is \n   RA(J2000) = 08h 57m 30s\n   Dec(J2000) = +45d 07' 32\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a complex\nstructure with a duration of about 30 sec.  The peak count rate\nwas ~1200 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until T0+55.3\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is A. Tohuvavohu (aaron.tohu 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/)\n\n",
