Circular_text TITLE: GCN CIRCULAR NUMBER: 36635 SUBJECT: GRB 240607A: BALROG localization (Fermi Trigger 739450879 / GRB 240607459) DATE: 24/06/07 11:45:34 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 739450879 at 11:01:14 on 07 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) = 17.7 deg Decl.(2000.0) = -28.8 deg The 1 sigma statistical error radius is 0.9 deg. We estimate an additional systematic error of 1 deg.

Circular_text TITLE: GCN CIRCULAR NUMBER: 36637 SUBJECT: GRB 240607A: Fermi GBM detection of a very bright burst DATE: 24/06/07 13:01:40 GMT FROM: Sarah Dalessi at UAH S. Dalessi (UAH) reports on behalf of the Fermi GBM Team: "At 11:01:14.31 UT on 7 June 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240607A (trigger 739450879/240607459). The final localization can be found in GCN 36634. The GBM light curve consists of three bright pulses, with the bulk of the emission during the first 15 seconds, and continued emission out to roughly 30 seconds. This event is a very bright GRB (up to 10,000 counts/s over 50-300 keV) and follow-up across all wavelengths is encouraged. The on-ground calculated location, using the Fermi GBM trigger data, is RA = 17.8, Dec = -32.1 (J2000 degrees, equivalent to J2000 01h 11m, -32d 06'), with a statistical uncertainty of 1.0 degrees. (radius, 1-sigma containment, statistical only; there is additionally a systematic error which we have characterized as a core-plus-tail model, with 90% of GRBs having a 3.7 deg error and a small tail suffering a larger than 10 deg systematic error. [Connaughton et al. 2015, ApJS, 216, 32] ). The angle from the Fermi LAT boresight is 109.0 degrees.

Waratkar (IITB), V. Jethwani (IITB), A. Dasgupta (BITS Hyderabad), J. Joshi (IUCAA), A. Vibhute (IUCAA), V. Bhalerao (IITB), D. Bhattacharya (Ashoka University/IUCAA), A. R. Rao (IUCAA/TIFR), and S. Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration: Analysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of the bright long-duration GRB 240607A which was also detected by Fermi-GBM (GCN Circ. 36634). The source was clearly detected in the CZT detectors in the 20-200 keV energy range. The light curve showed multiple peaks of emission with the strongest peak at 2024-06-07 11:01:25.500 UTC. The measured peak count rate associated with the burst is 880 (+57, -64) counts/s above the background in the combined data of all quadrants, with a total of 3987 (+214, -257) counts. The local mean background count rate was 447 (+5, -5) counts/s. Using cumulative rates, we measure a T90 of 12.3 (+0.3, -0.4) s. It was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve showed multiple peaks of emission with the strongest peak at 2024-06-07 11:01:24.9 UTC. The measured peak count rate is 4919 (+128, -137) counts/s above the background in the combined Veto data of all quadrants, with a total of 23001 (+510, -531) counts. The local mean background count rate was 1474 (+5, -5) counts/s. We measure a T90 of 12.6 (+0.2, -0.2) s from the cumulative Veto light curve. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, URSC, IUCAA, SAC, and PRL. The Indian Space Research Organisation funded, managed, and facilitated the project. CZTI GRB detections are reported regularly on the payload site at: http://astrosat.iucaa.in/czti/?q=grb

Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 11:01:14.31 UT on 07 June 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240607A (trigger 739450879/240607459), which was also detected by AstroSat (G. Waratkar et al. 2024, GCN 36638) and INTEGRAL/SPI-ACS (trigger #10733). The final localization can be found in GCN 36634 as well as the notice of a bright burst (S. Dalessi et al. 2024, GCN 36637). The angle from the Fermi LAT boresight is 109 degrees. The GBM light curve three pulses with a duration (T90) of about 20.2 s (50-300 keV). The time-averaged spectrum from T0+0.002 to T0+27.136 s is best fit by a Band function with Epeak = 247 +/- 4 keV, alpha = -0.92 +/- 0.01, and beta = -2.69 +/- 0.07. The event fluence (10-1000 keV) in this time interval is (9.2 +/- 0.5)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+11 s in the 10-1000 keV band is 95.8 +/- 0.8 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/"

Gardner on on behalf of the GRS-Odyssey GRB team, report: The very bright, long-duration GRB 240607A (Fermi-GBM detection: The Fermi GBM team, GCN 36634; Dalessi, GCN 36637; Dalessi and Meegan, GCN 36641; BALROG localization: Preis et al., GCN 36635; AstroSat-CZTI detection detection: Waratkar et al., GCN 36638) was detected by Fermi (GBM trigger 739450879), AstroSat (CZTI), Konus-Wind, INTEGRAL (SPI-ACS), Swift (BAT), and Mars-Odyssey (HEND) at about 39674 s UT (11:01:14). The burst was outside the coded field of view of the BAT. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 17.830 (01h 11m 19s) -29.324 (-29d 19' 25") Corners: 17.686 (01h 10m 45s) -29.329 (-29d 19' 45") 18.025 (01h 12m 06s) -29.401 (-29d 24' 04") 17.974 (01h 11m 54s) -29.317 (-29d 19' 03") 17.634 (01h 10m 32s) -29.245 (-29d 14' 41") --------------------------------------------- The error box area is 78 sq. arcmin, and its maximum dimension is 22 arcmin (the minimum one is 4.2 arcmin). The Sun distance was 76 deg. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM final and the BALROG localizations. This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB240607_T39674/IPN The HEALPix triangulation map is the multi-order HEALPix in units of probability density.

The burst light curve shows a multipeaked structure which starts at ~T0-0.2 s and has a total duration of ~24.7 s. The emission is seen up to ~6 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB240607_T39674/ As observed by Konus-Wind, the burst had a fluence of 1.03(-0.06,+0.05)x10^-4 erg/cm2, and a 64-ms peak flux, measured from T0+10.960 s, of 3.02(-0.33,+0.34)x10^-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-averaged spectrum of the burst (measured from T0 to T0+29.440 s) is best fit in the 20 keV - 10 MeV range by the GRB (Band) model with the following parameters: the low-energy photon index alpha = -0.94(-0.05,+0.05), the high energy photon index beta = -2.92(-0.42,+0.22), the peak energy Ep = 248(-13,+13) keV (chi2 = 111/98 dof). The spectrum near the maximum count rate (measured from T0+10.752 to T0+11.264 s) is best fit in the 20 keV - 10 MeV range by the GRB (Band) model with the following parameters: the low-energy photon index alpha = -0.21(-0.18,+0.19), the high energy photon index beta = -2.77(-0.37,+0.20), the peak energy Ep = 249(-24,+31) keV (chi2 = 54/46 dof). All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.

According to the GECAM-C light curve, this burst shows multiple pulses with a total duration of ~30 sec. We note that these results are very preliminary. Refined analysis will be reported later. Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission originally consists of two microsatellites (GECAM-A and GECAM-B) launched in December 2020. As the third member of GECAM constellation, GECAM-C was launched onboard SATech-01 experimental satellite in July 2022. GECAM mission is funded by the Chinese Academy of Sciences (CAS).
