Andreas von kienlin (MPE) and George Younes (USRA/MSFC) report on behalf of the Fermi GBM Team: "At 07:04:38.33 UT on 29 03 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140329A (trigger 417769481 / 140329295). The trigger resulted in an Autonomous Repoint Request (ARR), but FERMI went into SAA 120 seconds after trigger. The on-ground calculated location, using the GBM trigger data, is RA = 149.8, DEC = -27.44 (J2000 degrees), with an uncertainty of 1 degree (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 114 degrees. This burst was also independently detected by INTEGRAL SPI-ACS. The GBM light curve consists of two pulses seperated by about 25 seconds with a duration (T90) of about 21.5 s (50-300 keV). The time-averaged spectrum from T0-2.3 s to T0+33.6 s is best fit by a Band function with Epeak = 244 +/- 5 keV, alpha = -0.83 +/- 0.01, and beta = -2.38 +/- 0.04. The event fluence (10-1000 keV) in this time interval is (7.07 +/- 0.05)E-5 erg/cm^2. The 1-sec peak photon flux measured starting from T0+23.6 s in the 8-1000 keV band is 102.0 +/- 1.0 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
