Roberts (NASA/MSFC) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 23:13:45.38 UT on 30 November 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241130A (trigger 754701230/241130968). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 100.29, Dec = -26.38 (J2000 degrees, equivalent to J2000 6h 41m, -26d 22'), with a statistical uncertainty of 1.00 degrees. (radius, 1-sigma containment, statistical only; there is additionally a systematic error which we have characterized as a mixture of two Gaussians, one with a radius of 1.8 degrees (52% contribution) and one with a radius of 4.1 degrees (47% contribution) [A. Goldstein et al. 2020, ApJ, 895, 1]). The angle from the Fermi LAT boresight is 95 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 4.6 s (50-300 keV). The time-averaged spectrum from T0+0 to T0+4.544 s is best fit by a Band function with Epeak = 320 +/- 30 keV, alpha = -0.92 +/- 0.04, and beta = -2.04 +/- 0.07. The event fluence (10-1000 keV) in this time interval is (1.09 +/- 0.02)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+0.22 s in the 10-1000 keV band is 33.6 +/- 0.5 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/"

McKenna, D. Murphy, C. de Barra, A. Ulyanov, M. Doyle, R. Dunwoody, J. Mangan, G. Finneran, G. Corcoran, L. Cotter, A. Empey, J. Fisher, F. Gibson Kiely, J. Thompson, D. McKeown, A. Martin-Carrillo, L. Hanlon, S. McBreen, on behalf of the EIRSAT-1 team: EIRSAT-1 reports the detection of the long gamma-ray burst GRB241130A by the Gamma-ray Module (GMOD) instrument, which was also reported by Fermi GBM (GCN 38421 and 38406). The GMOD detection was made at 24-11-30 23:13:44.3 UTC. The GMOD light curve for GRB241130A, with 1.2s binning, shows a single peak. The spacecraft location at time of detection was 36.002 N, 21.890 W and an altitude of 453 km. The light curve for this event as measured by GMOD can be found here: https://grb.eirsat1.ie/241130A/241130A_LC_onboard_preliminary.png A bright FRED-like pulse can also be seen in the SPI-ACS ([Rau et al, Astronomy & Astrophysics, 438(3). 1175-1183. 2005](https://www.aanda.org/articles/aa/abs/2005/30/aa3159-05/aa3159-05.html)) light curve at a consistent time (SPI-ACS data can be retrieved using the following [link](https://www.astro.unige.ch/mmoda/?DEC=-29.74516667&RA=265.97845833&T1=2024-11-30T23%3A10%3A00.000&T2=2024-11-30T23%3A20%3A00.000&T_format=isot&data_level=ordinary&instrument=spi_acs&product_type=spi_acs_lc&query_status=new&query_type=Real&selected_catalog=&src_name=1E+1740.7-2942&time_bin=0.2&time_bin_format=sec)). EIRSAT-1 is Ireland’s first satellite ([Doyle et al. Proceedings of the 4th SSEA, 2022](https://researchrepository.ucd.ie/bitstreams/2f3fdccb-6e36-4ac1-88cd-4e80feecf446/download)). It is a 2U CubeSat and carries onboard a number of experiments including the Gamma-Ray Module (GMOD), a novel, compact Gamma-ray detector ([Murphy et al, Experimental Astronomy, 53, 961–990, 2022](https://link.springer.com/article/10.1007/s10686-022-09842-z)). GMOD consists of a 25 mm × 25 mm × 40 mm Cerium Bromide scintillator coupled to SiPMs and is designed to detect gamma-ray bursts in the ~ 60 keV - 1.5 MeV range. EIRSAT-1 was developed in University College Dublin with support from ESA’s Fly Your Satellite! programme and was launched on 1st December 2023.

Svinkin, and T. Cline on behalf of the Konus-Wind team, A. Goldstein, M. S. Briggs, C. Wilson-Hodge, and E. Burns on behalf of the Fermi GBM team, and E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report: The long-duration GRB 241130A (Fermi-GBM detection: The Fermi GBM team, GCN 38405, Sharma et al., GCN 38421; EIRSAT-1 GMOD Detection: McDermott et al., GCN 38423) was detected by Fermi (GBM trigger 754701230), Konus-Wind, INTEGRAL (SPI-ACS), and EIRSAT-1 (GMOD) at about 83625 s UT (23:13:45). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 111.465 (07h 25m 52s) -31.442 (-31d 26' 30") Corners: 120.603 (08h 02m 25s) -25.812 (-25d 48' 42") 122.268 (08h 09m 04s) -26.450 (-26d 27' 01") 99.058 (06h 36m 14s) -35.673 (-35d 40' 23") 96.603 (06h 26m 25s) -34.608 (-34d 36' 30") --------------------------------------------- The error box area is 31 sq. deg, and its maximum dimension is 23.5 deg (the minimum one is 1.4 deg). The Sun distance was 108 deg. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM localization (GCN 38405). This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB241130_T83628/IPN The HEALPix triangulation map is the multi-order HEALPix in units of probability density. The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.

Circular_text TITLE: GCN CIRCULAR NUMBER: 38429 SUBJECT: Konus-Wind detection of GRB 241130A DATE: 24/12/03 12:50:12 GMT FROM: Dmitry Frederiks at Ioffe Institute D. Frederiks, A.Lysenko, A. Ridnaia, D. Svinkin, A. Tsvetkova, M. Ulanov, and T. Cline, on behalf of the Konus-Wind team, report: The long GRB 241130A (Fermi-GBM detection: The Fermi GBM team, GCN 38405, Sharma et al., GCN 38421; EIRSAT-1 GMOD Detection: McDermott et al., GCN 38423; IPN triangulation: Ridnaia et al., GCN 38424) triggered Konus-Wind (KW) at T0=83628.376 s UT (23:13:48.376). The burst light curve shows a single, FRED-like pulse, which starts at ~T0-0.5 s, peaks at ~T0+0.3 s, and has a total duration of ~10 s. The emission is seen up to ~2 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB241130_T83628/ As observed by Konus-Wind, the burst had a fluence of (1.52 ± 0.21)x10^-5 erg/cm^2 and a 64-ms peak energy flux, measured from T0 + 0.384 s, of (1.77 ± 0.22)x10^-5 erg/cm^2/s (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum (measured from T0 to T0+8.448 s) is best fit in the 20 keV - 15 MeV range by a power law with exponential cutoff (CPL) model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -1.25(-0.08,+0.09) and Ep = 663(-128,+185) keV (chi2 = 66/81 dof). Fitting this spectrum by a Band function yields the same values of alpha and Ep, and an upper limit on the high energy photon index beta of -2.4 (chi2 = 66/80 dof). All the quoted errors are estimated at the 90% confidence level. All the presented results are preliminary.

The burst signal was seen by all CGBM detectors. Because of a problem with the ground alert processing script, the GCN notice was not distributed automatically for this event. The burst light curve shows a single pulse that starts at T-0.4 sec, peaks at T+0.1 sec, and ends at T+5.9 sec. The T90 and T50 durations measured by the SGM data are 5.4 +/- 0.8 sec and 2.4 +/- 0.5 sec (40-1000 keV), respectively. The ground-processed light curve is available at https://cgbm.calet.jp/cgbm_trigger/ground/1417043611 The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at Waseda University.
