Vetere (PSU)\nreport on behalf of the Swift Team:\n\nAt 21:07:15 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 090129 (trigger=341504). The BAT on-board calculated \nlocation is RA, Dec 269.092, -32.826 which is \n   RA(J2000) = 17h 56m 22s\n   Dec(J2000) = -32d 49' 32\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a FRED-like\nstructure with a duration of about 20 sec.  The peak count rate\nwas ~7000 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nDue to an observing constraint, Swift cannot slew to the BAT position. \nThere will thus be no XRT or UVOT data for this trigger until\nat least 03 Feb 2009. \n\nBurst Advocate for this burst is H. Ziaeepour (hz 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.)",
