Circular_text TITLE: GCN CIRCULAR NUMBER: 16042 SUBJECT: GRB 140329A: Fermi GBM observation of a bright burst DATE: 14/03/30 04:31:55 GMT FROM: George A. Younes at USRA/NASA/MSFC 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."

Connaughton, M. S. Briggs, C. Meegan, V. Pelassa, and A. Goldstein, on behalf of the Fermi GBM team, report: The long-duration, bright GRB 140329A (von Kienlin and Younes, GCN Circ. 16042) has been observed by Fermi (GBM), Konus-Wind, INTEGRAL (SPI-ACS), MESSENGER (GRNS), and Mars Odyssey (HEND), so far, at about 25478 s UT (07:04:38). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 146.246 (09h 44m 59s) -32.103 (-32d 06' 09") Corners: 145.867 (09h 43m 28s) -31.797 (-31d 47' 49") 145.948 (09h 43m 47s) -32.076 (-32d 04' 33") 146.627 (09h 46m 31s) -32.404 (-32d 24' 13") 146.544 (09h 46m 10s) -32.127 (-32d 07' 39") --------------------------------------------- The error box area is 491 sq.arcmin, and its maximum dimension is 53 arcmin (the minimum one is 12 arcmin). The center of the GBM ground position (von Kienlin and Younes, GCN Circ. 16042) is 5.6 deg from the center of the box. This box can be improved.

Circular_text TITLE: GCN CIRCULAR NUMBER: 16046 SUBJECT: Konus-Wind observation of GRB 140329A DATE: 14/03/30 16:56:28 GMT FROM: Valentin Pal'shin at Ioffe Inst S. Golenetskii, R.Aptekar, D. Frederiks, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, and T. Cline on behalf of the Konus-Wind team, report: A long-duration, very intense GRB 140329A (Fermi-GBM detection: von Kienlin & Younes, GCN 16042; IPN triangulation: Hurley at al., GCN 16045) triggered Konus-Wind at T0=25481.877 s UT (07:04:41.877). The burst light curve starts with a short pulse at ~T0 followed by a bright multi-peaked complex from ~T0+19 s to ~T0+30 s. The emission is seen up to ~10 MeV. As observed by Konus-Wind, the burst had a fluence of 8.5(-0.7,+0.7)x10^-5 erg/cm2, and a 64-ms peak flux, measured from T0+23.744 s, of 2.7(-0.3,+0.3)x10^-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-averaged spectrum (measured from T0 to T0+33.024 s) is best fit in the 20 keV - 18 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -1.04 (-0.09,+0.11), the high energy photon index beta = -2.30 (-0.17,+0.11), the peak energy Ep = 238 (-28,+32) keV, chi2 = 132/95 dof. The spectrum near the maximum count rate (measured from T0+23.296 to T0+23.808 s) is best fit in the 20 keV - 18 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -0.90 (-0.11,+0.13), the high energy photon index beta = -2.7 (-1.1,+0.3), the peak energy Ep = 388 (-66,+75) keV, chi2 = 68.0/80 dof. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB140329_T25481/ All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.

Circular_text TITLE: GCN CIRCULAR NUMBER: 16047 SUBJECT: GRB 140329A: Fermi-LAT detection DATE: 14/03/30 21:25:29 GMT FROM: Daniel Kocevski at GSFC D. Kocevski (NASA/Goddard), G. Vianello (Stanford U.), E. Bissaldi (University & INFN Trieste), and J. McEnery (NASA/Goddard) report on behalf of the Fermi-LAT team: An on-ground analysis of the IPN triangulation of GRB 140329A (Hurley et. al. GCN16045), which was detected by Fermi-GBM (trigger 417769481, GCN 16042) and initiated an autonomous repoint of the spacecraft, has revealed long-lived high-energy emission detected by Fermi-LAT. The best LAT on-ground location is found to be: RA, Dec 145.698, -32.229 (J2000) with an error radius of 0.2 deg (90% containment, statistical error only). The burst was outside the LAT field of view at the time of trigger and remained so for an additional 2000 seconds. The analysis above covers a period from 2000s to 5000s post GBM trigger and an energy range of 100 MeV to 10 GeV. The Fermi-LAT point of contact for this burst is D. Kocevski (daniel.kocevski@nasa.gov). The Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.
