"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-230524A (https://gcn.gsfc.nasa.gov/gcn3/0.gcn3) in a time range of 1000 seconds centered on the alert event time (2023-05-24 11:01:16.240 UTC to 2023-05-24 11:17:56.240 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-230524A. 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-230524A 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 (2023-05-23 11:09:36.240 UTC to 2023-05-25 11:09:36.240 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-230524A 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\nbe reached at roc@icecube.wisc.edu.\n\n[1] IceCube Collaboration, R. Abbasi et al., ApJ 910 4 (2021)\n\n",

To increase the duty cycle and the downlink rate, the upgrade of the on-board data acquisition software stack is in progress. The ground segment is also supported by the radio amateur community and it takes advantage of the SatNOGS network for increased data downlink volume. \n\n",

Sinapius (DESY) on behalf of the Fermi-LAT collaboration:\n\nWe report an analysis of observations of the vicinity of the IC230725A high-energy neutrino event (GCN 34261) with all-sky survey data from the Large Area Telescope (LAT), on board the Fermi Gamma-ray Space Telescope. The IceCube event was detected on 2023-07-25 at 21:30:51.06 UT (T0) with J2000 position RA = 327.04 (+2.27, -2.03) deg, Decl. = 12.33 (+1.80, -1.36) deg (90% PSF containment). There is one Fermi 4FGL-DR3 cataloged gamma-ray (>100 MeV; The Fermi-LAT collaboration 2022, ApJS, 260, 53) source in the 90% IC230725A uncertainty localization region. This is 4FGL J2150.8+1118 associated with the BL Lac object NVSS J215051+111915, located at 1.2 deg from the IC230725A position. Based on a preliminary analysis of the LAT data over a month and day timescale prior T0, this object is not significantly detected at gamma rays.\n\nWe searched for intermediate (days to years) timescale emission from a new gamma-ray source. Preliminary analysis indicates no significant (> 5 sigma) new excess emission (> 100 MeV) at the IC230725A best-fit position. Assuming a power-law spectrum (photon index = 2.0 fixed) for a point source at the IC230725A best-fit position, the >100 MeV flux upper limit (95% confidence) is < 3.5e-10 ph cm^-2 s^-1 for ~15-years (2008-08-04 to 2023-07-25 UTC), and < 5.3e-9 (< 7.3e-8) ph cm^-2 s^-1 for a 1-month (1-day) integration time before T0.\n\n\nSince Fermi normally operates in an all-sky scanning mode, regular monitoring of this region will continue. For these observations the Fermi-LAT contact persons are S. Garrappa (simone.garrappa at weizmann.ac.il), C. Bartolini (chiara.bartolini at ba.infn.it), S. Buson (sara.buson at uni-wuerzburg.de) and J. Sinapius (jonas.sinapius at desy.de).\n\nThe Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.\n\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwNTAzMTA5LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.DI3y7aLBQN3p0Af_cava1rtHV4y_59pWFHG4G-6CHdo\n\n",

"message_text": "Jada Vail, Maggie Li, Anna Ho (Cornell), Harsh Kumar, Vishwajeet Swain (IIT Bombay), Dmitry Svinkin (Ioffe Institute), Daniel Perley (LJMU):\n\nWe report the discovery of a fast-evolving red transient in Zwicky Transient Facility (ZTF) and GROWTH India Telescope (GIT) data.\n\nZTF23aamxeqf (AT2023jxk) was discovered at the position (J2000) of:\n\nRA = 17:02:36.97 (255.6540479 deg)\n\nDec = +51:52:05.09 (51.8680802 deg)\n\non 2023 June 5 by ZTF at g = 19.22 +/- 0.13 mag (MJD`100.20252). ZTF also obtained a detection ~1.6 hours later at r = 18.96 +/- 0.11 mag (MJD`100.26712). Forced photometry on P48 images revealed non-detections prior to discovery at g > 19.91 mag (MJD`099.45061) and r > 20.14 mag (MJD`099.40459), indicating a fast rise rate of >0.9 mag/day in g and >1.5 mag/day in r. Forced photometry also shows two detections later that night at g = 19.84 +/- 0.18 (MJD`100.44324) and r = 19.14 +/- 0.08 (MJD`100.42868), implying that the transient was red.\n\nThe fast rise and fall rates implied by ZTF photometry motivated us to trigger GIT for additional imaging. GIT imaging 1.5 days after the first ZTF detection showed a tentative (3-sigma) detection at r = 22.4 +/- 0.2 mag, indicating an average fading rate of 2.3 mag/day in r-band.\n\nThe Galactic latitude of AT2023jxk is 37.6 degrees, and the Galactic reddening towards the direction of AT2023jxk is: E_(g-r) = 0.032 from Schlafly & Finkbeiner (2011). There is no counterpart within 3 arcseconds in either Legacy Survey DR9 imaging or PS1 imaging.\n\nThe fast rise, fast decay, red color, and lack of archival optical counterpart of AT2023jxk make it a strong candidate afterglow. However, we did not identify any GRBs coincident with this position during the time window between the last non-detection and the first detection: Konus-Wind was observing the whole sky during the entire interval of interest (except ~1 hour between 05:58:03 - 06:58:16 on June 4) and did not detect any counterpart.\n\nAdditional observations, including photometry and spectroscopy, are encouraged to determine the nature of this transient.\n\n\nZTF is supported by the National Science Foundation under Grant No. AST-2034437 and a collaboration including Caltech, IPAC, the Weizmann Institute for Science, the Oskar Klein Center at Stockholm University, the University of Maryland, Deutsches Elektronen-Synchrotron and Humboldt University, the TANGO Consortium of Taiwan, the University of Wisconsin at Milwaukee, Trinity College Dublin, Lawrence Livermore National Laboratories, and IN2P3, France. Operations are conducted by COO, IPAC, and UW.\n\nThe GROWTH India Telescope (GIT; Kumar et al. 2022) is a 70-cm telescope with a 0.7-degree field of view, set up by the Indian Institute of Astrophysics (IIA) and the Indian Institute of Technology Bombay (IITB) with funding from DST-SERB and IUSSTF. It is located at the Indian Astronomical Observatory (Hanle), operated by IIA. We acknowledge funding by the IITB alumni batch of 1994, which partially supports the operations of the telescope.

"message_text": "S. Bala (USRA), C. Fletcher (USRA), O.J. Roberts (NASA/MSFC) and C. Meegan (UAH)\n report on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\n\"At 10:46:08.33 UT on 25 May 2023, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 230525A (trigger 706704373/230525449).\nThe Fermi GBM Final Real-time Localization was reported in GCN 33877.\n\nThe angle from the Fermi LAT boresight is 19 degrees.\n\nThe GBM light curve consists of single peak with a duration (T90)\nof 0.12 s (50-300 keV). The time-averaged spectrum\nfrom T0-0.06 to T0+0.06 s is best fit by\na power law function with an exponential high-energy cutoff.\nThe power law index is -0.80 +/- 0.09 and the cutoff energy,\nparameterized as Epeak, is 789 +/- 148 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(8.6 +/- 0.4)E-07 erg/cm^2. The 64-ms peak photon flux measured\nstarting from T0-0.064 s in the 10-1000 keV band is 25 +/- 1 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"\n\n",

Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data with the ML pipeline (Abraham et al., 2021, MNRAS, 504, 3084) and the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of a bright GRB 230608A which was also detected by CALET (ID Num. 1370284460), INTEGRAL SPI-ACS (Trig Num. 10282), and AGILE (Longo et al., GCN Circ. 33946).\n\nThe source was clearly detected in the 20-200 keV energy range. The light curve peaks at 2023-06-08 18:34:37.50 UTC. The measured peak count rate associated with the burst is 724 (+54, -54) counts/s above the background in the combined data of three quadrants (out of four), with a total of 3349 (+393, -345) counts. The local mean background count rate was 358 (+2, -3) counts/s. Using cumulative rates, we measure a T90 of 16 (+8, -8) 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 2023-06-08 18:34:37.50 UTC. The measured peak count rate associated with the burst is 1210 (+85, -95) counts/s above the background in the combined data of all quadrants, with a total of 4297 (+722, -809) counts. The local mean background count rate was 1573 (+6, -7) counts/s. We measure a T90 of 7 (+7, -3) s from the cumulative Veto light curve.\n\nCZTI 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.\n\nCZTI GRB detections are reported regularly on the payload site at:\nhttp://astrosat.iucaa.in/czti/?q=grb\n\n",

The T90 duration measured by GRBAlpha is 13 s and the overall significance during T90 reaches 8 sigma.\n\nThe light curve obtained by GRBAlpha is available here: https://grbalpha.konkoly.hu/static/share/GRB240128A_GCN.pdf\n\nAll GRBAlpha detections are listed at: https://monoceros.physics.muni.cz/hea/GRBAlpha/ \nGRBAlpha, launched on 2021 March 22, is a demonstration mission for a future CubeSat constellation (Werner et al. Proc. SPIE 2018). The detector of GRBAlpha consists of a 75 x 75 x 5 mm3 CsI scintillator read out by a SiPM array, covering the energy range from ~50 keV to ~1000 keV. To increase the duty cycle and the downlink rate, the upgrade of the on-board data acquisition software stack is in progress. The ground segment is also supported by the radio amateur community and it takes advantage of the SatNOGS network for increased data downlink volume. \n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/35649.",

Meegan (UAH) report on behalf of\nthe Fermi Gamma-ray Burst Monitor Team:\n\n\"At 10:10:31 UT on 14 June 2023, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 230614C (trigger 708430236/230614424) which\nwas also detected by INTEGRAL SPI-ACS (trigger 10284).\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 229.21, Dec = 10.30 (J2000 degrees, equivalent to\nJ2000 15h 16m, +10d 18'), with a statistical uncertainty of 1.00 degree\n(radius, 1-sigma containment, statistical only; there is additionally a systematic error\nwhich we have characterized as a core-plus-tail model, with 90% of GRBs having a\n3.7 deg error and a small tail suffering a larger than 10 deg systematic error\n[Connaughton et al. 2015, ApJS, 216, 32]).\n\nThe angle from the Fermi LAT boresight is 108 degrees.\n\nThe GBM light curve consists of a single emission episode with a duration (T90)\nof about 6.1 s (50-300 keV). The time-averaged spectrum\nfrom T0+0.003 to T0+7.488 s is best fit by\na Band function with Epeak = 196 +/- 7 keV,\nalpha = -0.50 +/- 0.04, and beta = -2.44 +/- 0.08.\n\nThe event fluence (10-1000 keV) in this time interval is\n(4.04 +/- 0.06)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+1.8 s in the 10-1000 keV band is 32.6 +/- 0.5 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"\n\n",

Nuttall, E. Pallé, report on behalf of the GOTO collaboration:\n\n\nWe report on observations of the fast fading transient candidate ZTF23aaoohpy/AT2023lcr (Swain et al, GCN 34022). The field was covered three times by the Gravitational-wave Optical Transient Observer (GOTO; Steeghs et al. 2021) between 2023-06-17 and 2023-06-18. We detect the reported transient in an observation taken at 01:27:41 UT on 2023-06-18 (5.1 hours before the ZTF discovery) with a magnitude of 18.77+/- 0.06 in the GOTO L-band (400 â 700nm). The source was not detected in the previous epoch at 23:50:30 UT on 2023-06-17 to a 5-sigma limiting magnitude of L > 20.3. The measured rise is therefore > 1.5 magnitudes in 1h45m, and constrains the onset to between these two epochs. The GOTO L-band is approximately g+r, and therefore taking the first ZTF epoch of detection to be L ~ 19.5, our detection implies a fading rate of ~0.75 mag over 0.2 days - significantly faster than the 1mag/day between the two ZTF epochs.\n\n\nImages were processed immediately after acquisition using the GOTO pipeline. Difference imaging was performed using recent survey observations of the same pointings. Magnitudes were calibrated using ATLAS-REFCAT2 (Tonry et al. 2018) and not corrected for Galactic extinction.\n\n\nGOTO (https://goto-observatory.org) is a network of telescopes operated at the Roque de los Muchachos Observatory on La Palma, Spain and Siding Spring Observatory in NSW, Australia; on behalf of a consortium including the University of Warwick, Monash University, Armagh Observatory & Planetarium, the University of Leicester, the University of Sheffield, the National Astronomical Research Institute of Thailand (NARIT), University of Turku, University of Portsmouth, University of Manchester and the Instituto de Astrofisica de Canarias (IAC)\n\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg3MjA0MzU5LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.hafiPA1A2Nl2U4FrIGMH7KInYtvk-oiGdc8-i01qcc8\n\n",
