Using cumulative rates, we measure a T90 of 15 (+5, -3) s.\n\nThe source was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve peaks at 2023-09-11 04:25:51.83 UTC. The measured peak count rate associated with the burst is 790 (+75, -76) counts/s above the background in the combined data of all quadrants, with a total of 4781 (+532, -605) counts. The local mean background count rate was 1400 (+6, -7) counts/s.

"message_text": "Samuele Ronchini (PSU), Jamie A. Kennea (PSU), James DeLaunay (U Alabama), Aaron Tohuvavohu (U Toronto), Gayathri Raman (PSU), Tyler Parsotan (NASA GSFC) report:\n\nSwift/BAT did not localize GRB 230913A onboard (T0: 2023-09-13T07:56:12.16 UTC, Fermi/GBM GCN 34680, CALET trigger 1378626813).\n\nThe Fermi and CALET notices, 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 with a sqrt(TS) of 19.7.\nAn arcminute localization is found with DeltaLLHOut of 64.99 and a DeltaLLHPeak of 60.07.\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 = 267.349, +74.484 deg (J2000) which is\nRA (J2000) 17h 49m 23.8s\nDec (J2000) 74d 29m 2.4s\nwith an estimated uncertainty of 5 arcmin radius.\n\nNo XRT and UVOT follow-up can be done due to observational constraints.\nWe strongly encourage follow-up from other telescopes.\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/\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34683.\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk0NjEzMzU5LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.zlxdDqmamf5wDo1qBWaHcfU6zTPUaU1GVoHhto5mvv0\n\n",

The 3-sigma upper limit achieved is ~ 43 micro Jy.\n\nWe would like to thank the staff of the uGMRT for approving, executing,\nand processing the observations through the DDT proposal (ddtC304; PI- Shraddha Mohnani).\n\nThe uGMRT is operated by the National Center for Radio Astrophysics of the Tata Institute of Fundamental Research.\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34727.\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk1MDM3MzA1LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.neAW8cOe9pNDJikWRpqQLGb4n70qKWk2ye4vUTXLzeI\n\n",

"message_text": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nA search for track-like muon neutrino events detected by IceCube consistent with the sky\nlocalization of the low-significance gravitational wave candidate S231025a in a time range of 1000 seconds\ncentered on the alert event time (2023-10-25 03:03:04 UTC to 2023-10-25 03:19:44 UTC)\nhas been performed [1,2]. During this time period IceCube was collecting good quality data.\nOne hypothesis test was conducted for this low-significance gravitational wave event. The\nsearch uses a Bayesian approach to quantify the joint GW + neutrino event significance, which\nassumes a binary merger scenario and accounts for known astrophysical priors, such as GW source\ndistance, in the significance estimate [3].\n\nTwo track-like events are found in spatial and temporal coincidence with the gravitational-wave\ncandidate S231025a calculated from the map circulated by LVK as S231025a-2-Preliminary. This\nrepresents an overall pre-trial p-value of 0.0010 for the Bayesian search.\n\nThe reported p-value here does not account for any trials correction (multiple hypotheses testing). The false alarm rate of these coincidences can be obtained by multiplying the p-values with their corresponding GW trigger rates. Further details are available at https://gcn.nasa.gov/missions/icecube and at https://roc.icecube.wisc.edu/public/LvkNuTrackSearch.\n\n\nProperties of the coincident event(s) are shown below.\n\ndt(s)\tRA(deg)\t\tDec(deg)\tAngular uncertainty(deg) p-value(generic transient) p-value(Bayesian)\n-----------------------------------------------------------------------------------------------------\n-331.09 226.87 -4.88 1.81 not applicable\t\t0.0253\n+284.41 240.49 -3.37 2.06 not applicable\t\t0.0011\n\n\n\nwhere:\ndt = Time of track event minus time of GW trigger (sec)\nAngular uncertainty = Angular uncertainty of track event: the radius of a circle\n \trepresenting 90% CL containment by area.\np-value = the p-value for this specific track event from each search.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the\ngeographic South Pole, Antarctica.
