Ukwatta (LANL)\nreport on behalf of the Swift Team:\n\nAt 13:54:58 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 150413A (trigger=637899).  Swift did not slew immediately \nto the burst due to an observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 190.385, +71.824 which is \n   RA(J2000) = 12h 41m 32s\n   Dec(J2000) = +71d 49' 26\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a multi-peaked\nstructure with a duration of about 120 sec.  The peak count rate\nwas ~1100 counts/sec (15-350 keV), at ~2 sec after the trigger. \n\nDue to an observing constraint, Swift cannot observe until\nT0+4 days. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is C. B. Markwardt (Craig.Markwardt 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.)",
