Siegel (PSU) report on behalf of the Neil Gehrels Swift\nObservatory Team:\n\nAt 04:19:22 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 181123A (trigger=873178).  Swift could not slew to the\nburst due to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 284.651, -8.237 which is \n   RA(J2000) = 18h 58m 36s\n   Dec(J2000) = -08d 14' 13\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is usual for an image trigger, there is\nno obvious variation in the immediately-available BAT lightcurve. \n\nDue to an observing constraint, Swift will not be able to slew\nto the burst until February 19. There will therefore be no XRT or\nUVOT data on this burst. \n\nBurst Advocate for this burst is A. Y. Lien (amy.y.lien AT nasa.gov). \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/too.html.)",
