TITLE: GCN CIRCULAR NUMBER: 43074 SUBJECT: IceCube-251210A: Upper limits from a search for additional neutrino events in IceCube DATE: 25/12/12 05:49:23 GMT FROM: Sam Hori at IceCube/U Wisc-Madison <sahori(a)wisc.edu> The IceCube Collaboration (http://icecube.wisc.edu/) reports: IceCube has performed a search [1] for additional track-like muon neutrino events arriving from the direction of IceCube-251210A (https://gcn.nasa.gov/circulars/43064) in a time range of 1000 seconds centered on the alert event time (2025-12-10 10:57:54.429 UTC to 2025-12-10 11:14:34.429 UTC) during which IceCube was collecting good quality data. Excluding the event that prompted the alert, zero track-like events are found within the 90% containment region of IceCube-251210A. We report a p-value of 1.00 in this time window. IceCube’s sensitivity to neutrino point sources with an E^-2.5 spectrum, expressed as E^2 dN/dE evaluated at 1 TeV, is 1.4e-01 GeV cm^-2 within the 90% spatial containment region of IceCube-251210A in a 1000 second time window. 90% of events IceCube would detect from a source at this declination with an E^-2.5 spectrum have energies in the approximate energy range between 2e+02 GeV and 9e+04 GeV. A subsequent search was performed including 2 days of data centered on the alert event time (2025-12-09 11:06:14.429 UTC to 2025-12-11 11:06:14.429 UTC). In this case, we report a p-value of 1.00, consistent with no significant excess of track events. IceCube’s sensitivity to neutrino point sources with an E^-2.5 spectrum, expressed as E^2 dN/dE evaluated at 1 TeV, is 1.7e-01 GeV cm^-2 within the 90% spatial containment region of IceCube-251210A in a 2 day time window. The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica. The IceCube realtime alert point of contact can be reached at roc(a)icecube.wisc.edu. [1] IceCube Collaboration, R.

TITLE: GCN CIRCULAR NUMBER: 43068 SUBJECT: GRB 251209A: Fermi GBM observation DATE: 25/12/10 22:23:56 GMT FROM: Elisabetta Bissaldi at Politecnico and INFN Bari <elisabetta.bissaldi(a)ba.infn.it> E. Bissaldi (Politecnico and INFN Bari) reports on behalf of the Fermi GBM Team: "At 13:24:03.99 UT on 9 December 2025, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 251209A (trigger 786979448 / 251209558). The Fermi GBM Final Real-time Localization is reported in GCN 43048. The angle from the Fermi LAT boresight at the GBM trigger time is 52 degrees. The GBM light curve consists of several structured emission episodes with a duration (T90) of about 57 s (50-300 keV). The time-averaged spectrum from T0-4 s to T0+81 s is best fit by a Band function with Epeak = 105 +/- 4 keV, alpha = -1.63 +/- 0.01, and beta = -2.37 +/- 0.06. The event fluence (10-1000 keV) in this time interval is (6.89 +/- 0.05)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+49.7 s in the 10-1000 keV band is 38.4 +/- 0.6 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/" View this GCN Circular online at https://gcn.nasa.gov/circulars/43068. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0L…

Rao (IUCAA/TIFR), and S. Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration: Analysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of a long, bright GRB 251209A which was also detected by Fermi GBM (Fermi GBM Team, GCN Circ. 43048). The source was clearly detected in the CZT detectors in the 20-200 keV energy range. The light curve peaks at 2025-12-09 13:24:31.50 UTC. The measured peak count rate associated with the burst is 358 (+38, -34) counts/s above the background in the combined data of three quadrants (out of four), with a total of 5908 (+328, -277) counts. The local mean background count rate was 208 (+1, -2) counts/s. Using cumulative rates, we measure a T90 of 38 (+4, -3) s. In the preliminary analysis, we find 594 Compton events associated with this event. The source was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve peaks at 2025-12-09 13:24:35.75 UTC. The measured peak count rate associated with the burst is 435 (+68, -32) counts/s above the background in the combined data of all quadrants, with a total of 6675 (+484, -624) counts. The local mean background count rate was 1160 (+3, -3) counts/s. We measure a T90 of 33 (+5, -3) s from the cumulative Veto light curve. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, URSC, IUCAA, SAC, and PRL. The Indian Space Research Organisation funded, managed, and facilitated the project.
