[vsnet-grb-info 41440] EP260105b/EP-WXT trigger 01709251028: Einstein Probe detection of an X-ray transient

TITLE: GCN CIRCULAR NUMBER: 43349 SUBJECT: EP260105b/EP-WXT trigger 01709251028: Einstein Probe detection of an X-ray transient DATE: 26/01/07 13:08:28 GMT FROM: EP Team at NAOC/CAS <ep_ta(a)bao.ac.cn> X. X. Sun, G. J. Yang, M. J. Liu, , C. C. Jin, Y. Liu (NAO, CAS) on behalf of the Einstein Probe (EP) team: We report on the detection of an X-ray transient by the Wide-field X-ray Telescope (WXT) on board the Einstein Probe (EP) mission, designated EP260105b. The transient triggered EP-WXT (ID: 01709251028) at 2026-01-05T18:47:36 (UTC). The WXT position of the source is R.A. = 158.387 deg, DEC = 17.616 deg (J2000) with an uncertainty of 3 arcmin in radius (90% C.L. statistical and systematic). In a previous Circular (Yang et al. , GCN 43340) , this event was tentatively classified as a stellar flare associated with ET Leo, based on the preliminary localization and flux estimation available at that time. After refined data processing and ground analysis of the WXT and FXT observations, we find that the evnet is unlikely to be a stellar flare from ET Leo. We find a short-timescale X-ray varability in the WXT refined telemetry data, therefore classify this event as an X-ray transient. A follow-up observation with the Follow-up X-ray Telescope (FXT) was performed automatically. Within the WXT error circle, an uncatalogued X-ray source was detected at R.A. = 158.3695 deg, DEC = 17.6123 deg (J2000) with an uncertainty of 10 arcsec in radius (90% C.L. statistical and systematic). A significant decay was detected in the light curve during the initial phase of FXT observation. The average 0.5-10 keV spectrum can be fitted with an absorbed power law with a fixed Galactic hydrogen column density of 2.97 x 10^20 cm^-2 and a photon index of 2.18(-0.87,0.92). The derived average unabsorbed 0.5-10 keV flux is 2.6 (-0.94/+2.59) x 10^(-13) erg/s/cm^2. Further multiwavelength follow-up observations are encouraged to clarify the physical nature of this transient. Launched on January 9, 2024, EP is a space X-ray observatory to monitor the soft X-ray sky with X-ray follow-up capability (Yuan et al. 2022, Handbook of X-ray and Gamma-ray Astrophysics).

TITLE: GCN CIRCULAR NUMBER: 43346 SUBJECT: GRB 260105B: Fermi GBM Detection DATE: 26/01/07 00:08:46 GMT FROM: Matt Godwin <msg0028(a)uah.edu> Matt Godwin (UAH) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 23:21:36.55 UT on 05 January 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260105B (trigger 789348101/260105973). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 259.71, Dec = 1.74 (J2000 degrees, equivalent to J2000 17h 18m, +1d 44'), with a statistical uncertainty of 2.03 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 68 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 11 s (50-300 keV). The time-averaged spectrum from T0-1.9 to T0+12.5 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.96 +/- 0.01 and the cutoff energy, parameterized as Epeak, is 232 +/- 2 keV. The event fluence (10-1000 keV) in this time interval is (8 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+2.4 s in the 10-1000 keV band is 156 +/- 2 ph/s/cm^2. A Band function fits the spectrum equally well with Epeak= 178 +/- 2 keV, alpha = -0.83 +/- 0.01 and beta = -2.19 +/- 0.03. 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/43346. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0L…

Hall, Brendan O'Connor (CMU), Daniel Gruen (LMU), and Antonella Palmese (CMU) report: We observed the 90% FXT localization of EP260105a (Zhou et al., GCNs 43327 and 43333) with the Three Channel Imager (3KK) at the Fraunhofer Telescope at Wendelstein Observatory (FTW) in the r and i-band simultaneously for 10 x 180 s starting at 2026-01-06T02:04:38 UT (0.84 days after the trigger). We performed difference imaging with templates from the DESI Legacy Surveys and did not detect any uncatalogued sources to a 3-sigma upper limit of r > 22.7 AB mag. The non-detection is consistent with the reports by Lipunov et al. (GCN 43328), Corcoran et al. (GCN 43332), and Li et al (GCN 43337). The magnitude is calibrated against the PS1 catalog and not corrected for Galactic extinction. We thank Christoph Ries from the Wendelstein Observatory for obtaining these observations.

TITLE: GCN CIRCULAR NUMBER: 43342 SUBJECT: GRB 260105A: SVOM/GRM observation DATE: 26/01/06 08:30:22 GMT FROM: Yue Wang <m18509381757(a)163.com> SVOM/GRM team: Yue Wang, Chen-Wei Wang, Hao-Xuan Guo, Shi-Jie Zheng, Yue Huang, Shao-Lin Xiong, Shuang-Nan Zhang (IHEP) SVOM/ECLAIRs team: Sebastien Guillot (IRAP) Report on behalf of the SVOM team: SVOM/GRM was triggered on-ground by GRB 260105A at 2026-01-05T22:47:16.000 (T0), which is also detected by Fermi/GBM (Fermi GBM team, GCN #43335). With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of multiple pulses with a T90 of 69 +16/-12 s in the 15-5000 keV band. The SVOM/GRM light curve can be found here: https://www.bursthub.cn//admin/static/svgrb260105A.png In addition, the position of this burst, as determined by Fermi/GBM (RA = 64.5, Dec = 55.5, Error = 3.3, GCN #43335), is located at about 85 degrees from the SVOM optical axis, which is outside the ECLAIRs field of view. With this localization, the time-averaged spectrum from T0-7 to T0+83 s is best fitted by a power law function. The power law index is -1.64 +0.08/-0.07. The event fluence (10-1000 keV) in this time interval is (1.85 +0.20/-0.20)E-05 erg/cm^2. 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: Yue Wang (IHEP) (yuewang(a)ihep.ac.cn) View this GCN Circular online at https://gcn.nasa.gov/circulars/43342. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0L…
