Goldsten, on behalf of the MESSENGER NS GRB team:\n\n\nAt 15:39:31 UTC, Swift-BAT detected a rate increase due to GRB 101129A\n(BAT trigger #439471. Only a sub-threshold image source was found\nonboard.  This event corresponds to Fermi GBM trigger #312737973. The\nIPN was alerted.  In ground analysis, the source was detected with\nslightly greater confidence at RA, Dec 155.921, -17.645 which is:\n\nRA (J2000)       10h 23m 41s\nDec (J2000)    -17d 38m 42s\n\nwith an estimated uncertainty radius of 3 arcmin (90% containment).\nCorrelation of Swift-BAT counting rates and SPI-ACS counting rates,\nand SPI-ACS with Messenger yielded intersecting annuli consistent with\nthis position. The burst was also detected by Suzaku-WAM.\n\nAs seen in BAT, the burst consisted of a single pulse with a T90 of about\n0.35 +- 0.05 sec.\n\nThe burst was faint and short. The low-number statistics in BAT make a\nfit to the spectrum very uncertain. The photon index was approximately\n0.8 +- 0.5.  The fluence was approximately (9 +- 5) x 10^-08 ergs/cm^2.\n\nA Swift TOO observation was executed at 11 hours after the burst.  The\nlocation of the burst was observed by the Swift-XRT and Swift-UVOT for\na total of about 1400 seconds.  No afterglow was detected.  No further\nobservations are planned.",
