Siegel (PSU) report on\nbehalf of the Neil Gehrels Swift Observatory Team:\n\nAt 11:42:32 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 230723B (trigger=1180410).  \nThe BAT on-board calculated location is \nRA, Dec 250.379, -5.327 which is \n   RA(J2000) = 16h 41m 31s\n   Dec(J2000) = -05d 19' 37\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single-peaked\nstructure with a duration of about 10 sec.  The peak count rate\nwas ~2200 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until T0+50.2\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is K. L. Page (klp5 AT leicester.ac.uk). \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",
