Vetere (PSU) report on behalf of the Swift Team:\n\nOn 2009-03-12 at 06:17:00 UT, the Swift Burst Alert Telescope (BAT) \ntriggered on Swift trigger 346250.  Swift did not slew immediately to the event\ndue to an earth-limb constraint. The BAT on-board calculated location\nis RA, Dec 282.112, +36.758 which is \n   RA(J2000) = 18h 48m 27s\n   Dec(J2000) = +36d 45' 28\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed nothing significant. \nGiven the low significance (5.72 sigma) we do not believe that this event\nis a real GRB.  Swift will not be able to observe with the Swift narrow-field\ninstruments until ~48 minutes after the trigger.",
