Marshall (NASA/GSFC),\nK. L. Page (U Leicester), D. M. Palmer (LANL), A. M. Parsons (GSFC),\nB. A. Rowlinson (U Leicester) and L. Vetere (PSU) report on behalf of\nthe Swift Team:\n\nAt 00:00:59 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 090401 (trigger=348128).  The BAT on-board calculated \nlocation is RA, Dec 350.909, +29.767 which is \n   RA(J2000)  =  23h 23m 38s\n   Dec(J2000) = +29d 46' 00\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows a small peak at\n~T+30 sec and then two large peaks at ~T+100 and ~T+120 sec. \nThe peak count rate was ~4000 counts/sec (15-350 keV), at ~120 sec\nafter the trigger. \n\nDue to an observing constraint, Swift cannot slew to\nthe BAT position. It will not be possible to observe\nuntil 2nd May due to a sun constraint. There will thus \nbe no XRT or UVOT data for this trigger. \n\nBurst Advocate for this burst is P. Schady (ps AT mssl.ucl.ac.uk). \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.)",
