Williams (PSU)\nreport on behalf of the Neil Gehrels Swift Observatory Team:\n\nAt 21:19:34 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 231110A (trigger=1195733).  Swift did not slew immediately \nto the burst due to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 356.296, +82.621 which is \n   RA(J2000) = 23h 45m 11s\n   Dec(J2000) = +82d 37' 16\"\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 20 sec.  The peak count rate\nwas ~2800 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until T0+50.7\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is V. D'Elia (valerio.delia AT ssdc.asi.it). \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",
