  "body": "\nJ. A. Kennea (PSU) report on behalf of the Neil Gehrels Swift\nObservatory Team:\n\nAt 03:46:30 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated Swift J151857.0-572147 (trigger=1218696).  Swift did not \nslew to the source due to engineering activities. No XRT or UVOT data\nwill be collected. The BAT on-board calculated location is \nRA, Dec 229.705, -57.346 which is \n   RA(J2000) = 15h 18m 49s\n   Dec(J2000) = -57d 20' 45\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a [**double-peaked**]\nstructure with a duration of about TTT sec.  The peak count rate\nwas ~1070 counts/sec (15-350 keV), at ~-1 sec after the trigger. \n\n"
