Circular_text TITLE: GCN CIRCULAR NUMBER: 38265 SUBJECT: GRB 241117A: Fermi GBM Detection DATE: 24/11/17 20:47:14 GMT FROM: Lorenzo Scotton at UAH L. Scotton (UAH) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 03:00:43.23 UT on 17 November 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241117A (trigger 753505248/241117125). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 2.04, Dec = 16.33 (J2000 degrees, equivalent to J2000 0h 8m, +16d 19'), with a statistical uncertainty of 1.74 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 58 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 8.9 s (50-300 keV). The time-averaged spectrum from T0-0.3 to T0+9.86 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.46 +/- 0.07 and the cutoff energy, parameterized as Epeak, is 724 +/- 62 keV. The event fluence (10-1000 keV) in this time interval is (9.7 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+0.58 s in the 10-1000 keV band is 13.2 +/- 0.3 ph/s/cm^2. A Band function fits the spectrum equally well with Epeak = 708 +/- 68 keV, alpha = -0.45 +/- 0.07 and beta = -3.16 +/- 0.98. 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/"

With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that the main emission of this burst consists of multiple pulses with a duration of about 3.2 s, which is followed by a long soft extended emission lasting longer than 70 s. The GRM light curve can be found here: https://www.bursthub.cn//admin/static/svgrb241117A.png This burst is located at about 72 degrees from the SVOM optical axis, and outside the ECLAIRs field of view. The Space Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA, China), National Center for Space Studies (CNES, France) and the Chinese Academy of Sciences (CAS, China), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. GRM is developed by the Institute of High Energy Physics (IHEP) of CAS. The SVOM point of contact for this burst is: Chen-Wei Wang (IHEP)(cwwang@ihep.ac.cn)

Circular_text TITLE: GCN CIRCULAR NUMBER: 38273 SUBJECT: GRB 241117A: Swift/BAT-GUANO localization skymap of a burst DATE: 24/11/19 03:15:06 GMT FROM: Samuele Ronchini at PSU Samuele Ronchini (PSU), James DeLaunay (PSU), Aaron Tohuvavohu (Caltech), Gayathri Raman (PSU), Jamie A. Kennea (PSU), Tyler Parsotan (NASA GSFC) report: Swift/BAT did not localize GRB 241117A onboard (T0: 2024-11-17T03:00:43.23 UTC, Fermi GCN 38265, SVOM GCN 38266) The Fermi notice, distributed in near real-time, triggered the Swift Mission Operations Center operated Gamma-ray Urgent Archiver for Novel Opportunities (GUANO; Tohuvavohu et al. 2020, ApJ, 900, 1). Upon trigger by this notice, GUANO sent a command to the Swift Burst Alert Telescope (BAT) to save 200 seconds of BAT event-mode data from [-50,+150] seconds around the time of the burst. All the requested event mode data was delivered to the ground. The BAT likelihood search, NITRATES (DeLaunay + Tohuvavohu 2022, ApJ, 941, 169), performed on the temporal window [T0-20 s, T0+20 s], detects the burst with a sqrt(TS) of 17.36 in a 2.048 s analysis time bin, starting at T0 - 0.5119 s. Using the NITRATES analysis, parameter estimation was performed to obtain the localization of this burst in the form of a HEALPIX Multi-Order Coverage (MOC) skymap. This localization accounts for both statistical and systematic errors. More details in the creation and calibration of these maps will soon be published (DeLaunay et al. 2024. in prep) The 90% credible area is 1216 deg2 and the 50% credible area is 257 deg2. The integrated probability inside the coded field of view is <1%. The NITRATES skymap is consistent with the Fermi localization reported in the final position notice. The combined Fermi/GBM+NITRATES 90% credible area is 127 deg2 and the 50% credible area is 34 deg2. A plot of the probability skymap can be viewed here: [skymap_plot](https://guano.swift.psu.edu/trigger_report?id=753505277/#:~:text=Probability%20Skymap) The probability skymap file can be downloaded from the link here [skymap_fits_file](https://guano.swift.psu.edu/files/753505277/0_n_PROBMAP) Instructions on how to read and manipulate this map can be found here: https://guano.swift.psu.edu/documentation More details about this burst can be found on the trigger report page here: https://guano.swift.psu.edu/trigger_report?id=753505277 GUANO is a fully autonomous, extremely low latency, spacecraft commanding pipeline designed for targeted recovery of BAT event mode data around the times of compelling astrophysical events to enable more sensitive GRB searches.

Gardner on on behalf of the GRS-Odyssey GRB team, report: The long-duration (or possible short GRB with extended emission) GRB 241117A (Fermi-GBM detection: The Fermi GBM team, GCN 38258; Scotton and Meegan, GCN 38265; SVOM-GRM detection: Wang et al., GCN 38266; Swift-BAT/GUANO detection: Ronchini et al., GCN 38273) was detected by Fermi (GBM trigger 753505248), Konus-Wind, SVOM (GRM), INTEGRAL (SPI-ACS), Swift (BAT), and Mars-Odyssey (HEND), at about 10843 s UT (03:00:43). 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: 2.489 (00h 09m 57s) +16.049 (+16d 02' 55") Corners: 2.124 (00h 08m 30s) +16.504 (+16d 30' 14") 1.993 (00h 07m 58s) +16.881 (+16d 52' 52") 2.859 (00h 11m 26s) +15.576 (+15d 34' 33") 3.003 (00h 12m 01s) +15.166 (+15d 09' 59") --------------------------------------------- The error box area is 557 sq. arcmin, and its maximum dimension is 1.97 deg (the minimum one is 6 arcmin). The Sun distance was 130 deg. This localization may be improved. A triangulation map and HEALPix FITS file are posted at http://www.ioffe.ru/LEA/GRBs/GRB241117_T10845/IPN The HEALPix triangulation map is the multi-order HEALPix in units of probability density.
