The BAT light curve showed a single-peaked\nstructure with a duration of about 10 sec. The peak count rate\nwas ~2200 counts/sec (15-350 keV), at ~1 sec after the trigger.\n\nDue to an observing constraint, Swift will not slew until T0+50.2\nminutes. There will be no XRT or UVOT data until this time.\n\nBurst Advocate for this burst is K. L. Page (klp5 AT leicester.ac.uk).\nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/)\n\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwMTEzMjcwLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.JU2zfzucTCYsEEi2oVp93mBrYrcwVxD3DyusXEup6j8\n\n",

"message_text": "The LIGO Scientific Collaboration, the Virgo Collaboration, and the\nKAGRA Collaboration report:\n\nWe identified the compact binary merger candidate S230723ac during\nreal-time processing of data from LIGO Hanford Observatory (H1) and\nLIGO Livingston Observatory (L1) at 2023-07-23 10:18:34.451 UTC (GPS\ntime: 1374142732.451). The candidate was found by the, GstLAL\n[1], MBTA [2], and SPIIR [3] analysis pipelines.\n\n\nS230723ac is an event of interest because its false alarm rate, as\nestimated by the online analysis, is 5.3e-08 Hz, or about one in 7\nmonths. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/superevents/S230723ac\n\nThe classification of the GW signal, in order of descending\nprobability, is BBH (87%), Terrestrial (13%), NSBH (<1%), or BNS\n(<1%).\n\nAssuming the candidate is astrophysical in origin, the probability\nthat the lighter compact object is consistent with a neutron star mass\n(HasNS) is <1%. [4] Using the masses and spins inferred from the\nsignal, the probability of matter outside the final compact object\n(HasRemnant) is <1%. [4] Both HasNS and HasRemnant consider the\nsupport of several neutron star equations of state. The probability\nthat either of the binary components lies between 3 and 5 solar masses\n(HasMassgap) is <1%.\n\nTwo sky maps are available at this time and can be retrieved from the\nGraceDB event page:\n * bayestar.multiorder.fits,0, an initial localization generated by\nBAYESTAR [5], distributed via GCN notice about 25 seconds after the\ncandidate event time.\n * bayestar.multiorder.fits,1, an initial localization generated by\nBAYESTAR [5], distributed via GCN notice about 5 minutes after the\ncandidate event time.\n\nThe preferred sky map at this time is bayestar.multiorder.fits,1. For\nthe bayestar.multiorder.fits,1 sky map, the 90% credible region is\n1281 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 1686 +/- 515 Mpc (a posteriori mean\n+/- standard deviation).\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo/KAGRA Public Alerts User Guide\nhttps://emfollow.docs.ligo.org/userguide/.\n\n\n [1] Tsukada et al. arXiv:2305.06286 (2023) and Ewing et al. arXiv:2305.05625 (2023)\n [2] Aubin et al.

GCN 34234) with CAFOS at the 2.2m CAHA telescope, at Calar Alto Observatory, in Almeria (Spain). The observation consisted of 9x360s exposures in i-band, starting at 20:34 UT and with mean epoch on 0.389 days after the burst. We do not see any new source within the XRT error box (Page & Evans, GCN 34238) down to a 3-sigma limit of 23.0 mag. We do notice that there is a faint object at the Eastern edge of the XRT error box with a magnitude of 22.4 mag, with coordinates (J2000): 16:41:31.43, -5:20:05.7, but that seems to be also there, at a similar magnitude, in the PanSTARRS images. It is not possible at this time to determine if this object could be the host galaxy of GRB 230723B.\n\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwMTU3NTAzLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.oEeXV2_fqelSeetlSuJK1w5ic_ppAjB3DZgZc1D7dpM\n\n",
