The on-ground calculated location, using the Fermi GBM trigger data, is RA = 259.7, Dec = -4.8 (J2000 degrees, equivalent to J2000 17h 18m, -4d 47'), with a statistical uncertainty of 3.8 degrees. The angle from the Fermi LAT boresight is 97.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 35994 SUBJECT: GRB 240329A: BALROG localization (Fermi Trigger 733441392 / GRB 240329905) DATE: 24/03/29 22:04:21 GMT FROM: Jochen Greiner at MPE T. Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 733441392 at 21:43:07 on 29 March 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) = 248.9 deg Decl.(2000.0) = -1.4 deg The 1 sigma statistical error radius is 3.4 deg. We estimate an additional systematic error of 1 deg.

Circular_text TITLE: GCN CIRCULAR NUMBER: 36002 SUBJECT: GRB 240329A: Glowbug gamma-ray detection DATE: 24/04/01 15:06:52 GMT FROM: C.C. Cheung at Naval Research Lab C.C. Cheung, R. Woolf, M. Kerr, J.E. Grove (NRL), A. Goldstein (USRA), C.A. Wilson-Hodge, D. Kocevski (MSFC), and M.S. Briggs (UAH) report: The Glowbug gamma-ray telescope [1,2], operating on the International Space Station, reports the detection of GRB 240329A, which was also detected by Fermi/GBM (GCN 35993, 35994), GRBAlpha (GCN 35997), and AstroSat/CZTI (GCN 35999). Using an adaptive window with a resolution of 32-ms, the burst onset is determined to be 2024-03-29 21:43:05.936 with a duration of 7.1 s and a total significance of about 42 sigma. The light curve comprises two primary peaks at ~T0+1s and ~T0+4s, with a faint peak at ~T0+7s. The analysis results presented here are preliminary and use a response function that lacks a detailed characterization of the surrounding passive structure of the ISS. Glowbug is a NASA-funded technology demonstrator for sensitive, low-cost gamma-ray transient telescopes developed, built, and operated by the U.S. Naval Research Laboratory (NRL) with support from the University of Alabama in Huntsville, USRA, and NASA MSFC. It was launched on 2023 March 15 aboard the Department of Defense Space Test Program’s STP-H9 to the ISS. The detector comprises 12 large-area (15 cm x 15 cm) CsI:Tl panels covering the surface of a half cube, and two hexagonal (5-cm diameter, 10-cm length) CLLB scintillators, giving it a large field of view (instantaneous FoV ~2/3 sky) over a wide energy band of 50 keV to >2 MeV.
