"message_text": "SVOM/GRM team: Yue Wang, Chen-Wei Wang, Wen-Jun Tan, Shi-Jie Zheng, Yue Huang, Shao-Lin Xiong, Shuang-Nan Zhang (IHEP)\n\nSVOM/ECLAIRs team: Frédéric Daigne (IAP)\n\nReport on behalf of the SVOM team:\n\nSVOM/GRM was triggered in-flight by GRB 251208A (SVOM trigger reference: sb25120804) at 2025-12-08T09:25:58.000 (T0), which is also detected by Fermi/GBM (Fermi GBM team, GCN #43027). \n\nWith the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of a single pulse with a T90 of 2.2 +0.9/-0.5 s in the 15-5000 keV band.\n\nThe SVOM/GRM light curve can be found here:\nhttps://www.bursthub.cn//admin/static/svgrb251208A.png\n\nIn addition, the position of this burst, as determined by Fermi/GBM (RA = 32.8, Dec = -66.7, position uncertainty = 3.9, GCN #43027), is located at about 61 degrees from the SVOM optical axis, which is outside the ECLAIRs field of view. \n\nWith this localization, the time-averaged spectrum from T0-1 to T0+2 s is best fitted by a power law function with an exponential high-energy cutoff. The power law index is -1.20 +0.19/-0.18 and the cutoff energy, parameterized as Epeak, is 135 +51/-27 keV. The event fluence (10-1000 keV) in this time interval is (1.29 +0.19/-0.14)E-06 erg/cm^2. \n\nThe 1s peak spectrum, measured from T0-0.6 to T0+0.4 s, if fitted by a power law function with an exponential high-energy cutoff, the power law index is -0.98 +0.17/-0.18 and the cutoff energy, parameterized as Epeak, is 139 +33/-21 keV. The flux (10-1000 keV) in this time interval is (7.79 +0.91/-0.72)E-07 erg/cm^2/s.\n\nThe localization of GRB 251208A in the 'Amati' relation diagram is shown at: https://www.bursthub.cn//admin/static/svgrb251208A_amati.png\nThe localization of GRB 251201A in the 'Yonetoku' relation diagram is shown at: \nhttps://www.bursthub.cn//admin/static/svgrb251208A_yonetoku.png\n\nIn the absence of a measured redshift, the duration, soft spectrum, and position in the Amati diagram do not allow us to determine whether this burst is type I or type II.\n\nThe 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.\n\nThe SVOM/GRM point of contact for this burst is: Yue Wang (IHEP) (yuewang@ihep.ac.cn)\n",

The power law index is -0.54 +0.22/-0.19 and the cutoff energy, parameterized as Epeak, is 617 +241/-151 keV. The event fluence (10-1000 keV) in this time interval is (1.18 +0.09/-0.12)E-06 erg/cm^2. \n\nThe localization of GRB 251208C in the 'Amati' relation diagram is shown at: https://www.bursthub.cn//admin/static/svgrb251208C_amati.png\n\nThe 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.\n\nThe SVOM/GRM point of contact for this burst is: Chen-Wei Wang (IHEP) (cwwang@ihep.ac.cn)\n\n",

Four antennas, Pickmere (Pi), Darnhall (Da), Knockin (Kn), and Cambridge (Cm), participated in the observation.\n\nObserving setup:\n- Frequency coverage: 4.82–5.33 GHz (C band), total bandwidth 512 MHz\n- Antennas: Pi, Da, Kn, Cm\n- Polarizations: Right and left circular\n- Spectral setup: 4 × 128 MHz spectral windows, 128 × 1 MHz channels per window (post-averaging)\n- Observation span: 2025-12-03 17:40 UT to 2025-12-05 04:19 UT\n\nThe data were processed using the standard e-MERLIN pipeline followed by calibration and imaging in CASA.\n\nNo significant radio emission was detected at the position of GRB 251129A. We place a 3σ upper limit of 0.066 mJy beam⁻¹ on the flux density.\n\nWe encourage coordinated and continued radio follow-up to further constrain the flux density and probe potential variability at C band and complementary frequencies. We thank the e-MERLIN TAG and operations teams for their support.\n",

In the stacked image, we do not detect any new source within the ECLAIRs error circle.\n\nWe measure the following upper limits calibrated against the PanSTARRS DR1 catalog, and not corrected for Galactic extinction:\n\nr > 21.6 AB (mid-time 2.27 hr after the trigger);\nz > 19.7 AB (mid-time 2.65 hr after the trigger).\n\nThis project is funded by the SVOM collaboration.\n",

Automated analysis of the XRT data will be presented online at\nhttps://www.swift.ac.uk/ToO_GRBs/00021893\nAny uncatalogued X-ray sources detected in this analysis will be\nreported on this website and via GCN COUNTERPART notices. These are\nnot necessarily related to the Fermi/LAT event. Any X-ray source\nconsidered to be a probable afterglow candidate will be reported via a \nGCN Circular after manual consideration.\n\nDetails of the XRT automated analysis methods are detailed in Evans et\nal. (2007, A&A, 469, 379; 2009, MNRAS, 397, 1177 and 2014, ApJS, 210, 8).\n\nThis circular is an official product of the Swift-XRT team.\n\n",

Bartolini (UniTrento and INFN Bari) and F. Longo (University and INFN, Trieste) report on behalf of the Fermi-LAT team:\n\nAt 10:17:17.29 UT on December, 08, 2025 Fermi-LAT detected high-energy emission from GRB 251208B, which was also detected by Fermi-GBM (trigger 786881842 / 251208429, GCN #43028) and Swift/BAT-GUANO (GCN #43033).\n\nThe best LAT on-ground location is found to be\n\nRA, Dec = 228.48, 29.07 (J2000)\n\nwith an error radius of 0.07 deg (90 % containment, statistical error only), which is consistent with the Swift/BAT-GUANO localization.\n\nThis was 39 deg from the LAT boresight at the time of the trigger.\n\nThe data from the Fermi-LAT show a significant increase in the event rate that is spatially and temporally correlated with the trigger with high significance.\nThe photon flux above 100 MeV in the time interval 0 - 1 ks after the GBM trigger is (3.13 ± 0.09)E-6 ph/cm2/s. The estimated photon index above 100 MeV is -2.01 ± 0.23. The highest-energy photon is a 17 GeV event which is observed 419 seconds after the GBM trigger.\n\nA Swift ToO has been approved for this burst.\n\nThe Fermi-LAT point of contact for this burst is Chiara Bartolini (chiara.bartolini@ba.infn.it).\n\nThe Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.",

Kennea (PSU), Tyler Parsotan (NASA GSFC), Maia Williams (Northwestern) report:\n\nSwift/BAT did not localize GRB 251208B onboard (T0: 2025-12-08T10:17:17.29 UTC, Fermi Trig 786881842).\n\nThe 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). \n\nUpon 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.\n\nThe BAT likelihood search, NITRATES (DeLaunay + Tohuvavohu 2022, ApJ, 941, 169), detects the burst in a 8.192 s analysis time bin starting at T0 - 2.048 s with a sqrt(TS) of 17.6.\nAn arcminute localization is found with DeltaLLHOut of 43 and a DeltaLLHPeak of 30.0.\n\nSee Section 9.1 and Figures 10 and 17 in the NITRATES paper for brief descriptions and interpretations of sqrt(TS), DeltaLLHPeak, and DeltaLLHOut.\n\nThe BAT position is\nRA, Dec = 228.453, 29.044 deg which is\n RA(J2000) = 15h 13m 48.72s\n Dec(J2000) = 29d 02’ 38.4″\nwith an estimated uncertainty of 5 arcmin radius.\n\nMore details about this burst can be found on the trigger report page here:\n\nhttps://guano.swift.psu.edu/trigger_report?id=786881874\n\nXRT and UVOT follow-up has been requested.\nResults of follow-up observations will be reported in future circulars.\n\nGUANO is a fully autonomous, extremely low latency, spacecraft\ncommanding pipeline designed for targeted recovery of BAT event mode\ndata around the times of compelling astrophysical events to enable\nmore sensitive GRB searches.\n\nA live reporting of Swift/BAT event data recovered by GUANO can be\nfound at: https://www.swift.psu.edu/guano/",
