Zhang, on behalf of the ICRANet team, report:\n\n\nFollowing the BdHN classification [Aimuratov, et al., ApJ 955 (2023) 93] and the determination of the redshift z=2.2 of transient AT2023sva (de Ugarte Postigo, et al., GCN 34740), from the energetics evaluated by Liang Li (2023) from Fermi GBM data in (2.15+/-0.13)x10^{52} erg (see attached figure), we conclude that the source is a BdHN II (GRB230916A).\n\nWe Propose to look with the James Webb Space Telescope the appearance of the associated supernova (SN) on October 31 (+/-1 day), in order to extend the GRB-SN connection in the range 1<z<3 and verify the standard candle nature of SNe Ib/c.\n\nFigure: http://www.icranet.org/documents/GRB230916A.pdf\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34779.",

Gompertz et al. (GCN 34878) have reported a GOTO optical counterpart candidate, GOTO23baj (AT 2023vuc), at RA (J2000) = 00:55:07.30, Dec (J2000) = -15:15:19.43 and L = 18.37 +/- 0.07 on 2023-10-24 22:15:30.\n\nWe triggered Las Cumbres Observatory follow-up imaging and detected a source at the position of GOTO23baj on UT 2023-10-25 07:23:31 at SDSS r' = 18.28 +/- 0.12 in a single 300 sec exposure using one of the Las Cumbres Observatory 40 cm telescopes at Heleakala Observatory (Maui, Hawaii).\n\nThis transient has also been detected by ZTF (ZTF23abnevza) on UT 2023-10-25 07:42:27 at ZTF g = 18.193 ± 0.082.\n\nThis work makes use of observations from the Las Cumbres Observatory global telescope network (program IAC2023B-001) and is based on observations made with the Las Cumbres Observatory's education network telescopes that were upgraded through generous support from the Gordon and Betty Moore Foundation. These observations are part of a course in Astrophysical Techniques of the Master in Astrophysics of the Astrophysics Department of the University of La Laguna and Instituto de Astrofisica de Canarias (Tenerife, Canary Islands, Spain).\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34881.",

"message_text": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nIceCube has performed a search [1] for additional track-like muon neutrino events arriving from the direction of IceCube-240327A (https://gcn.nasa.gov/circulars/35983) in a time range of 1000 seconds centered on the alert event time (2024-03-27 10:56:29.920 UTC to 2024-03-27 11:13:09.920 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-240327A. The IceCube sensitivity to neutrino point sources with an E^-2.5 spectrum (E^2 dN/dE at 1 TeV) within the locations spanned by the 90% spatial containment region of IceCube-240327A is 1.3e-01 GeV cm^-2 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 3e+02 GeV and 1e+05 GeV.\n\nA subsequent search was performed including 2 days of data centered on the alert event time (2024-03-26 11:04:49.920 UTC to 2024-03-28 11:04:49.920 UTC). In this case, we report a p-value of 0.24, consistent with no significant excess of track events. The IceCube sensitivity to neutrino point sources with an E^-2.5 spectrum (E^2 dN/dE at 1 TeV) within the locations spanned by the 90% spatial containment region of IceCube-240327A is 1.5e-01 GeV cm^-2 in a 2 day time window.\n\nThe 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@icecube.wisc.edu.\n\n[1] IceCube Collaboration, R.

"message_text": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nIceCube has performed a search [1] for additional track-like muon neutrino events arriving from the direction of IceCube-240327B (https://gcn.nasa.gov/circulars/35984) in a time range of 1000 seconds centered on the alert event time (2024-03-27 16:04:10.470 UTC to 2024-03-27 16:20:50.470 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-240327B. The IceCube sensitivity to neutrino point sources with an E^-2.5 spectrum (E^2 dN/dE at 1 TeV) within the locations spanned by the 90% spatial containment region of IceCube-240327B ranges from 1.4e-01 to 1.5e-01 GeV cm^-2 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 3e+02 GeV and 2e+05 GeV.\n\nA subsequent search was performed including 2 days of data centered on the alert event time (2024-03-26 16:12:30.470 UTC to 2024-03-28 16:12:30.470 UTC). In this case, we report a p-value of 1.00, consistent with no significant excess of track events. The IceCube sensitivity to neutrino point sources with an E^-2.5 spectrum (E^2 dN/dE at 1 TeV) within the locations spanned by the 90% spatial containment region of IceCube-240327B is 1.6e-01 GeV cm^-2 in a 2 day time window.\n\nThe 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@icecube.wisc.edu.\n\n[1] IceCube Collaboration, R. Abbasi et al., ApJ 910 4 (2021)\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/36005.",
