Siegel (PSU)\nreport on behalf of the Swift Team:\n\nAt 05:10:03 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 090509 (trigger=351525).  Swift did not slew to this burst. \nThe BAT on-board calculated location is \nRA, Dec 241.404, -28.404 which is \n   RA(J2000)  =  16h 05m 37s\n   Dec(J2000) = -28d 24' 12\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows multiple peaks\nwith a duration of about 30 sec.  The peak count rate\nwas ~1300 counts/sec (15-350 keV), at ~20 sec after the trigger. \n\nDue to the Moon observing constraint, Swift cannot slew to the \nBAT position until May 12.  There will thus be no XRT or UVOT data \nfor this trigger. \n\nBurst Advocate for this burst is D. Grupe (grupe AT astro.psu.edu). \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.)",
