The real-time alert data and light curves of SVOM/GRM were downlinked to the ground through the VHF system with low latency. The light curves show that this burst consists of single pulse with a duration of about 0.2 s. The SVOM/GRM light curve can be found here: https://www.bursthub.cn//admin/static/svgrb241016B.png The SVOM/GRM on-ground localization of this burst is (J2000): RA: 38.48 deg DEC: 27.74 deg Error: 19.65 deg (1 sigma, statistical only) We caution that the calibration of SVOM/GRM is undergoing and this localization is subject to systematic errors. The localization may be improved in the refined analysis. At the time of the burst, ECLAIRs was not collecting data. 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/GRM point of contact for this burst is: Wen-Long Zhang (IHEP)(zhangwl@ihep.ac.cn)

Circular_text TITLE: GCN CIRCULAR NUMBER: 37806 SUBJECT: GRB 241016B: Swift/BAT-GUANO localization skymap of a short burst DATE: 24/10/17 19:35:35 GMT FROM: Jimmy DeLaunay at Penn State James DeLaunay (PSU), Aaron Tohuvavohu (U Toronto), Samuele Ronchini (PSU), Gayathri Raman (PSU), Jamie A. Kennea (PSU), Tyler Parsotan (NASA GSFC) report: Swift/BAT did not localize GRB 241016B onboard (T0: 2024-10-16 11:12:40.13 UTC, Fermi trig 750769965, GCN 37797, SVOM/GRM GCN 37803) 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 7.2 in a 0.128 s analysis time bin, starting at T0 - 0.064 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 16,614 deg2 and the 50% credible area is 7,705 deg2. The integrated probability inside the coded field of view is 2%. A plot of the probability skymap can be viewed here, [https://guano.swift.psu.edu/trigger_report?id=750769994/#:~:text=Probability%20Skymap](https://guano.swift.psu.edu/trigger_report?id=750769994/#:~:text=Probability%20Skymap) The probability skymap file can be downloaded from the link here, https://guano.swift.psu.edu/files/750769994/0_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=750769994 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.

Circular_text TITLE: GCN CIRCULAR NUMBER: 37813 SUBJECT: GRB 241016B: Fermi GBM Observations DATE: 24/10/18 13:32:44 GMT FROM: Elisabetta Bissaldi at Politecnico and INFN Bari E. Bissaldi (Politecnico and INFN Bari) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 11:12:40.13 UT on 16 October 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241016B (trigger 750769965/241016467), which was also detected by SVOM/GRM (Zhang et al. 2024, GCN 37803) and by Swift/BAT-GUANO (DeLaunay et al. 2024, GCN 37806). The angle from the Fermi LAT boresight is 86 degrees. The GBM light curve consists of two peaks with a duration (T90) of about 0.8 s (50-300 keV). The time-averaged spectrum from T0-0.6s to T0+0.7s is best fit by a power law function with an exponential high-energy cutoff. The power law index is 0.0 +/- 0.5 and the cutoff energy, parameterized as Epeak, is 840 +/- 380 keV. The event fluence (10-1000 keV) in this time interval is (4.1 +/- 0.5)E-07 erg/cm^2. The 64-msec peak photon flux measured starting from T0-0.064 s in the 10-1000 keV band is 6.4 +/- 0.7 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/"
