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",

Parameter estimation has been\nperformed using Bilby [1] and a new sky map, Bilby.multiorder.fits,0,\ndistributed via GCN Notice, is available for retrieval from the\nGraceDB event page:\n\nhttps://gracedb.ligo.org/superevents/S230723ac\n\nFor the Bilby.multiorder.fits,0 sky map, the 90% credible region is\n1117 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 1551 +/- 436 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] Ashton et al.

Le Flocâh, D. Götz (CEA Paris-Saclay), A.Saccardi, S.Vergani (GEPI, Obs. de Paris), S. Basa (LAM), report on behalf of a larger collaboration :\n\nWe observed the field of GRB 230723B (Page et al. GCN 34234) using the T193cm and T120cm telescopes at Observatoire de Haute-Provence (France). We obtained 26 exposures in the râ-band (4x30sec + 22x150sec) with MISTRAL on the T193cm for a total exposure time of 57min, starting at 20:54 UT with a mean epoch at ~0.42days after trigger. At the same time we also obtained 10 exposures of 6min in the I-band at T120cm (total time of 1h). In the râ-band and I-band combined frames, we do not detect any new source within the XRT error box (Page & Evans, GCN 34238). Our photometric calibration was performed using nearby stars from the PanSTARRS catalog, leading to the following lower limits :\n\nrâ > 21 mag (AB, 3 sigma)\nI > 19.25 mag (AB, 3 sigma)\n\nThese non-detections are consistent with the CAHA deeper observations in the i-band reported earlier by Agui Fernandez et al. (GCN 34241).\n\nWe acknowledge the excellent support from Observatoire de Haute-Provence, in particular Yoann Degot-Longhi, and we also thank Alice Morel.\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwMTkxODMzLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.c0BG55A9KE_uoFY0jiU9R0Xk9TMIMohfH-QltkBLmZg\n\n",

Dichiara (PSU),\n and P.A. Evans report on behalf of the Swift-XRT team:\n\nWe have analysed 6.5 ks of XRT data for GRB 230723B, from 3.3 ks to\n28.6 ks after the BAT trigger. The data are entirely in Photon\nCounting (PC) mode. Using 1149 s of PC mode data and 3 UVOT images, we\nfind an enhanced XRT position (using the XRT-UVOT alignment and\nmatching UVOT field sources to the USNO-B1 catalogue): RA, Dec 250.37810, -5.33463 which is equivalent to:\n\nRA (J2000): 16h 41m 30.74s\nDec(J2000): -05d 20' 04.7\"\n\nwith an uncertainty of 2.4 arcsec (radius, 90% confidence).\n\nThe light curve can be modelled with a power-law decay with a decay\nindex of alpha=1.6 (+0.6, -0.4).\n\nA spectrum formed from the PC mode data can be fitted with an absorbed\npower-law with a photon spectral index of 2.4 (+0.6, -0.5). The\nbest-fitting absorption column is 6.8 (+4.5, -3.3) x 10^21 cm^-2, in\nexcess of the Galactic value of 2.2 x 10^21 cm^-2 (Willingale et al.\n2013). The counts to observed (unabsorbed) 0.3-10 keV flux conversion\nfactor deduced from this spectrum is 4.0 x 10^-11 (9.4 x 10^-11) erg\ncm^-2 count^-1.\n\nA summary of the PC-mode spectrum is thus:\nTotal column:\t 6.8 (+4.5, -3.3) x 10^21 cm^-2\nGalactic foreground: 2.2 x 10^21 cm^-2\nExcess significance: 2.3 sigma\nPhoton index:\t 2.4 (+0.6, -0.5)\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/01180410.\n\nThis circular is an official product of the Swift-XRT team.\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwMjAyMjUwLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.Q-3zhqA_DXTw6jMQRl-UaMxdNVGbRhax1HgrA_Kaxs4\n\n",

Meegan (UAH) report on behalf of the Fermi GBM Team:\n\nAt 11:42:33.03 UT on 23 July 2023, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 230723B (trigger 711805358 / 230723488),\nwhich was also detected by Swift BAT (K. L. Page et al. 2023, GCN 34234).\nThe Fermi GBM on-ground location is consistent with the Swift BAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 78 degrees.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 10 s (50-300 keV).\nThe time-averaged spectrum from T0-2 s to T0+9 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff. The power law index is -0.9 +/- 0.1 and\nthe cutoff energy, parameterized as Epeak, is 59.1 +/- 2.7 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.8 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+1.2 s in the 10-1000 keV band\nis 7.8 +/- 0.4 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\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwMjA3MjI4LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.9K-UoGu2E5wmvShZJENsiSSJ04A0A7iyafBJJiMadvw\n\n",

GCN 34248) we noticed that the new localisation has very little overlap with the fist one. The revised localisation is no longer consistent with the object mentioned in our previous GCN (Agui Fernandez et al. GCN 34241). However, within the new localisation circle and outside the original one, we detect an object at coordinates (J2000): 16:41:30.65 -5:20:04.5 with an AB magnitude of i = 22.4+/-0.2 mag as compared to PanSTARRS field objects. No object is detected in PanSTARRS at this position. Further observations will be needed to confirm the object variability and its possible identification as the optical counterpart of GRB 230723A.\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjkwMjE4MzUwLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.5RGOrs4BlTK6o3Uip0Hma5rn8Ri1NJ5JsvoPJepD7ao\n\n",
