Circular_text TITLE: GCN CIRCULAR NUMBER: 36786 SUBJECT: GRB 240629A: Fermi GBM Final Real-time Localization DATE: 24/06/29 17:05:07 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 16:53:52 UT on 29 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240629A (trigger 741372837.729204 / 240629704). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 314.4, Dec = -35.7 (J2000 degrees, equivalent to J2000 20h 57m, -35d 42'), with a statistical uncertainty of 3.1 degrees. The angle from the Fermi LAT boresight is 79.0 degrees.

Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 741372837 at 16:53:52 on 29 June 2024 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60). The best-fit position is: RA(2000.0) = 317.4 deg Decl.(2000.0) = -47.8 deg The 1 sigma statistical error radius is 3.5 deg. We estimate an additional systematic error of 1 deg.

Circular_text TITLE: GCN CIRCULAR NUMBER: 37340 SUBJECT: GRB 240629A: First GRB Detected by BurstCube DATE: 24/08/29 17:00:16 GMT FROM: Judith Racusin at NASA/GSFC I. Martinez-Castellanos (GSFC/UMD/CRESST), A. Myers (GSFC/ORAU), D. Violette (GSFC/ORAU), L. Angellini (GSFC), J. Asercion (GSFC/ADNET), M. S. Briggs (UAH), R. Caputo (GSFC), J. Cox (GSFC), G. de Nolfo (GSFC), K. Gasaway (GSFC), S. Griffin (UWM), D. Hartmann (Clemson), B. A. Hristov (UAH), A. Joens (Berkeley), P. Nuessle (GSFC/GWU), J. S. Perkins (GSFC), J. Racusin (GSFC), S. Semper (GSFC), P. Shawhan (UMD), J. Smith (UAH), L. Tian (GSFC) on behalf of the BurstCube Team: At approximately 16:53 UTC on 29 June 2024, BurstCube detected GRB 240629A, also seen by Fermi-GBM (GCN 36786) and SVOM (GCN 36805). The spacecraft reported time was 16:53:28 UTC, with an approximate offset of -25 s from the GBM trigger time, which we attribute to BurstCube’s onboard clock uncertainty at the time of this data collection. This is the first GRB detected by BurstCube in a ground analysis of downlinked commissioning data. We analyzed our continuous binned data (16 energy channels, 256 ms time resolution) in the energy band of ~130-1000 keV, seeing a signal (total Test Statistic of 160.87) in excess of background in a 4.096 s window search in 3 detectors (Cs0, Cs1, Cs3). The 4 detector significances are 6.85, 9.61, 2.01, 4.19 sigma above background for Cs0, Cs1, Cs2, Cs3, respectively. The duration is T90 = 7.2 [-1.0, +1.8] seconds, with a single-pulse light curve consistent with that seen by Fermi-GBM. Localization and spectral analysis are ongoing. The BurstCube team continues to search our data for astronomical transients seen in at least two detectors, including independent events and those seen by other instruments. BurstCube is a 6U CubeSat built, managed, and operated by NASA Goddard Space Flight Center and funded by NASA/APRA. The BurstCube instrument is comprised of 4 CsI(Tl) scintillator detectors read out by arrays of SiPMs. It was launched on March 21, 2024 on the NASA CRS-30 to the ISS, and deployed on April 18, 2024.
