TITLE: GCN CIRCULAR NUMBER: 43673 SUBJECT: GRB 260208A: Fermi GBM Observation DATE: 26/02/09 20:09:35 GMT FROM: oindabimukherjee(a)gmail.com O. Mukherjee (USRA) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 05:07:28.24 UT on 08 February 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260208A (trigger 792220053/260208214), which was also detected by Fermi-LAT (F. Longo et al. 2026, GCN 43645), Swift XRT (S. Dichiara et al. 2026, GCN 43652), and NOT (Dimple et al. 2026, GCN 43662) with a spectroscopic redshift of z = 2.36. The Fermi GBM on-ground location is consistent with the Fermi-LAT position. The angle from the Fermi LAT boresight is 78 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 35.3 s (50-300 keV). The time-averaged spectrum from T0-3.6 to T0+66.0 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.87 +/- 0.01 and the cutoff energy, parameterized as Epeak, is 460 +/- 0.1 keV. The event fluence (10-1000 keV) in this time interval is (1.50 +/- 0.06)E-04 erg/cm^2. The 1-sec peak photon flux measured starting from T0+17 s in the 10-1000 keV band is 29.7 +/- 0.4 ph/s/cm^2. A Band function fits the spectrum equally well with Epeak= 328 +/- 1 keV, alpha = -0.76 +/- 0.01 and beta = -2 +/- 0.01. 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/" View this GCN Circular online at https://gcn.nasa.gov/circulars/43673. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0L…

TITLE: GCN CIRCULAR NUMBER: 43671 SUBJECT: GRB 260208B: Swift-XRT observations DATE: 26/02/09 16:03:40 GMT FROM: Phil Evans at U of Leicester <pae9(a)star.le.ac.uk> A.P. Beardmore (U. Leicester), J.P. Osborne (U. Leicester), P. D'Avanzo (INAF-OAB), M.G. Bernardini (INAF-OAB), E. Ambrosi (INAF-IASFPA), J.A. Kennea (PSU), D.N. Burrows (PSU), S. Lanava (PSU) and P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: Swift-XRT has performed follow-up observations of the Fermi/LAT-detected burst GRB 260208B, collecting 1.6 ks of Photon Counting (PC) mode data between T0+33.1 ks and T0+44.4 ks. One uncatalogued X-ray source has been detected within the estimated 3-sigma Fermi/LAT error region (354 arcsec), it is below the RASS limit and shows no definitive signs of fading. Details of this source are given below: Source 1: RA (J2000.0): 99.6189 = 06h 38m 28.55s Dec (J2000.0): -13.7743 = -13d 46' 27.4" Error: 3.1 arcsec (radius, 90% conf. [Enhanced position]) Count-rate: 0.0338 +/- 0.0067 ct s^-1 Distance: 238 arcsec from Fermi/LAT position. Flux: (1.63 +/- 0.32)e-12 erg cm^-2 s^-1 (observed, 0.3-10 keV) The flux reported by EP-WXT for this source at 74.7 ks after the trigger (GCN Circ. 43663) is about a factor of 10 fainter than this XRT measurement, however, which suggests it is indeed the GRB afterglow. The results of the XRT-team automatic analysis of the XRT observations, including a position-specific upper limit calculator, are available at https://www.swift.ac.uk/ToO_GRBs/00021909. We note that the large number of spurious sources was due to unusually high background. This circular is an official product of the Swift-XRT team.

TITLE: GCN CIRCULAR NUMBER: 43669 SUBJECT: GRB 260204A: Swift/UVOT Upper Limits DATE: 26/02/09 13:22:25 GMT FROM: Alice Breeveld at MSSL-UCL <a.breeveld(a)ucl.ac.uk> A.A. Breeveld (UCL-MSSL) and S. Laha (GSFC/UMBC) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of the SVOM/ECLAIRS-detected burst GRB 260204A (Pillas et al., GCN Circ. 43613) 2.3 ks after the trigger. The afterglow reported by Malesani et al. (in the r and z bands, GCN Circ. 43621) and Li et al. (GCN Circ. 43626) and consistent with XRT source 1 (Evans et al., GCN Circ. 43622) is not detected in the U-band exposures. Preliminary 3-sigma upper limit using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the initial exposure is: Filter T_start(s) T_stop(s) Exp(s) Mag u 23622 25281 1634 >20.8 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.023 in the direction of the burst (Schlegel et al. 1998).

Xing-Hao, GCN Circ. 43650), using the DDRAGO two-channel wide-field imager on the COLIBRÍ telescope. We observed from 2026-02-09T05:10:25 to 2026-02-09T06:30:45 UTC (from 19.3 to 20.6 hours after the trigger) and obtained 30 minutes of simultaneous exposure in the r, z filters. The data were reduced and coadded with the COLIBRÍ pipeline and analysed with STDWeb/STDPipe (Karpov 2025). The photometry was calibrated using nearby stars from the PanSTARRS DR1 catalog, is in the AB system, and is not corrected for Galactic extinction. We detect a source at the position of the SVOM/VT candidate (Li et al., GCN Circ. 43659), with the following preliminary magnitudes : r = 22.61 +/- 0.14 z = 21.99 +/- 0.25 Further analysis are ongoing. We thank the staff of the Observatorio Astronómico Nacional on the Sierra de San Pedro Mártir and the COLIBRÍ and DDRAGO engineering teams. COLIBRÍ is an astronomical observatory developed and operated jointly by France (AMU, CNES and CNRS) and Mexico (UNAM and SECIHTI). It is located at the Observatorio Astronómico Nacional on the Sierra de San Pedro Mártir, Baja California, Mexico.

The observations were started on 2026-02-08 at 20:52:28 UT, i.e., ~ 15.75 hours after the Fermi/GBM trigger. We detect an optical afterglow in a single 300s R-band exposure at the position reported by (Podesta et al. 2026, GCN 43640). We obtain the following preliminary magnitude in the stacked image: Date Start_UT T_start-T0 (hour) Filter Exp time (s) Magnitude =============================================================== 2026-02-08 20:52:28 ~15.75 R 300s*1 19.89 +/-0.04 The optical detection of the burst is consistent with Lipunov et al. 2026 (GCN 43637); Podesta et al. 2026 (GCN 43640); Wortley et al. 2026 (GCN 43641); Ma et al. 2026 (GCN 43655); Ahumada et al. 2026 (GCN 43657); and Dimple et al. 2026 (GCN 43661, 43662). The magnitude is not corrected for the Galactic extinction in the direction of the burst. Photometric calibration is performed using the standard stars from the USNO-B1.0 catalogue.

TITLE: GCN CIRCULAR NUMBER: 43664 SUBJECT: GRB 260208A: COLIBRÍ optical observations DATE: 26/02/09 11:14:54 GMT FROM: F. Magnani at Aix-Marseille Université, CPPM/CNRS <francesco.magnani.work(a)gmail.com> Francesco Magnani (CPPM), Leonardo García García (UNAM), Jean-Grégoire Ducoin (CPPM), Stéphane Basa (UAR Pytheas), William H. Lee (UNAM), Alan M. Watson (UNAM), Edilberto Aguilar-Ruiz (UNAM), Jean-Luc Atteia (IRAP), Camila Angulo (UNAM), Dalya Akl (NYUAD), Sarah Antier (IJCLAB), Rosa L. Becerra (UNAM), Nathaniel R.

The data were reduced and coadded and analysed with the COLIBRÍ pipeline. The photometry was calibrated using nearby stars from the PanSTARRS DR1 catalog, is in the AB system, and is not corrected for Galactic extinction. We detected the optical counterpart Lipunov et al. (GCN Circ. 43640), Wortley et al. (GCN Circ. 43641), Dichiara et al. (GCN Circ. 43652), Ma et al. (GCN Circ. 43655), Ahumada et al. (GCN Circ. 43657), Dimple et al. (GCN Circ. 43661), with measured redshift z = 2.36 (Dimple et al. GCN Circ. 43662) at a preliminary magnitude of: r = 21.09 +/- 0.04 z = 20.64 +/- 0.06 Further observations are ongoing. We thank the staff of the Observatorio Astronómico Nacional on the Sierra de San Pedro Mártir and the COLIBRÍ and DDRAGO engineering teams. COLIBRÍ is an astronomical observatory developed and operated jointly by France (AMU, CNES and CNRS) and Mexico (UNAM and SECIHTI). It is located at the Observatorio Astronómico Nacional on the Sierra de San Pedro Mártir, Baja California, Mexico.
