Steeghs, D. K. Galloway, V. Dhillon, P. O'Brien, D. Pollacco, K. Noysena, L. Nuttall, E. Pallé, report on behalf of the GOTO collaboration:\n\n\nWe report on optical observations with the Gravitational-wave Optical Transient Observer (GOTO; Steeghs et al. 2021) in response to the LIGO/Virgo candidate BNS event S230615az. Targeted observations covering 686 sqr. degrees or 24.1% of the localisation probability of the BAYESTAR skymap were performed between 21:16 UT June 15 and 00:35 UT June 16 2023 (3.43 to 6.75 hours after trigger).\n\n\nExposures were taken in L-band (400-700 nm passband) and the median 5 sigma depth was 20.3 AB magnitudes.\n\n\nImages were processed immediately after acquisition using the GOTO pipeline. Difference imaging was performed using recent survey observations of the same pointings. Source candidates were initially filtered using a classifier (Killestein et al. 2021) and cross-matched against a variety of contextual and minor planet catalogues. Human vetting was carried out in real time on any candidates that passed the above checks.\n\n\nWithin the 90% localisation region of the LVK skymap, we identify two priority candidate counterparts. Both are associated with catalogued galaxies that have photometric redshifts consistent with the GW distance posterior. We find no evidence of these sources prior to the GW alert in previous GOTO observations or the ZTF observations provided by the Lasair broker (Smith et al. 2019). We note possible low significance pre-GW flux in the ATLAS forced photometry server (Shingles et al. 2021) for GOTO23hn.\n\n\nName | RA(J2000) | Dec(J2000) | Filter | Mag(AB) | D_L(Mpc) | Catalog\n\nGOTO23hn | 12:40:35.55 | +17:02:15.27 | L | 19.49 +/- 0.10 | 278.0 | WISExSuperCOSMOS\n\nGOTO23hu | 13:22:55.23 | +08:09:49.57 | L | 19.43 +/- 0.08 | 245.6 | GLADE+\n\n\nMagnitudes were calibrated using ATLAS-REFCAT2 (Tonry et al. 2018) and not corrected for Galactic extinction.\n\n\nObservations are ongoing.\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---\nTo unsubscribe, open this link in a web browser:\n[object Promise]\n\n",

In this case, we report a p-value of 0.38, consistent with no significant excess of track events. IceCube's sensitivity assuming an E^-2 spectrum (E^2 dN/dE) to neutrino point sources within the locations spanned by the 90% spatial containment of the 4-Update map ranges from 0.028 to 1.219 GeV cm^-2 in this time window.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica.

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 with a sqrt(TS) of 29.2 in a 0.128 s analysis time bin.\n\nNITRATES results are consistent with a burst coming from outside the FOV, with DeltaLLHOut of -1.\n\nSee Section 9.1 and Figures 10 and 17 in the NITRATES paper for brief descriptions and interpretation of sqrt(TS), DeltaLLHPeak, and DeltaLLHOut.\n\nGUANO is a fully autonomous, extremely low latency, spacecraft commanding pipeline designed for targeted recovery of BAT event mode data around the times of compelling astrophysical events to enable more sensitive GRB searches.\n\nA live reporting of Swift/BAT event data recovered by GUANO can be found at: https://www.swift.psu.edu/guano/\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg2OTczOTM4LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.BV8pXh-3xweTs-17lruaBptiimHTYVIdJdzb9ZvYgHU\n\n",

Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of a bright short GRB 230616A which was also detected by INTEGRAL/SPI-ACS (Trig 10287) and Swift/BAT-GUANO (Tohuvavohu et al., GCN Circ. 33982).\n\nThe source was clearly detected in the 20-200 keV energy range. The light curve peaks at 2023-06-16 20:37:58.765 UTC. The measured peak count rate associated with the burst is 6385 (+1349, -1043) counts/s above the background in the combined data of all quadrants, with a total of 307 (+42, -47) counts. The local mean background count rate was 431 (+29, -43) counts/s. Using cumulative rates, we measure a T90 of 0.06 (+0.01, -0.01) s.\n\nThe source was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range.\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\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg2OTgxNDU1LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.H32S7mD9K3-00HnulEoZUKmG5vkFIZI4T0hAgjA7tpQ\n\n",

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\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg2OTg2ODY2LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.3Rw2ogKSnqGH39YcwrHzz6xvIZPOM7QLZoA1CGwUvD0\n\n",

Paek (SNU ARC/SNU), Myungshin Im (SNU ARC/SNU), and Hyun-Il Sung (KASI), on behalf of the GECKO Team\n\nWe report the optical observations conducted with the LOAO telescopes of two optical counterpart candidates, GIT230615aa, and GIT230615ab (H. Kumar, GCN 33974) of the LIGO/Virgo/KAGRA gravitational-wave event, S230615az. The LOAO is a 1.0-meter class telescope in the USA. The LOAO observation started at 2023-06-16 05:03 (UT) or about 0.46 days after the GW alert in R-band. We calibrated flux with the PANSTARRS catalog and used an AB magnitude system. As a result, we could not detect any significant signals from the candidates. Furthermore, observations taken approximately 0.8 days after the GW alert also reported the non-detection of both candidates (Z.P. Zhu, GCN 33981). The preliminary 5 sigma depths of these images are below:\n\nOBJECT DATE-OBS[UTC] t-t0[days] FILTER EXPTIME DEPTH\nGIT230615aa 2023-06-16T05:03:20 0.46 R 180s*10 21.0\nGIT230615ab 2023-06-16T05:23:51 0.48 R 180s*10 20.8\n\nGravitational-wave EM Counterpart Korean Observatory (GECKO) is a network of 10+ 0.5m to 1m class telescopes worldwide.

"message_text": "A. Santos (CBPF/Fermilab), C. D. Kilpatrick (Northwestern), C. R. Bom (CBPF), Eduardo Lacerda (IAG-USP) report on behalf of the STEP-GW collaboration:\n\nWe conducted an optical search for candidate counterparts in the localization region of LVK gravitational wave event S230615az with the T80S 0.8-m robotic telescope using the 1.4 x 1.4 field-of-view camera. The tiling was optimally determined using the latest localization map from the LVK and galaxy catalogs in Teglon (Coulter et al., in prep.). In total, T80S observed 24 fields (68 individual exposures at total) within the 90th percentile localization region of S230615az. All of our completed pointings have been uploaded to the GW Treasure Map (Wyatt et al., 2020) at https://treasuremap.space/alerts?graceids=S230615az.\n\nSubtracting DECam and SkyMapper template images from the T80S images using photpipe (Rest et al., 2005), we identified the following candidate counterpart in our imaging:\n\nName MJD RA(deg) Dec(deg) Filter Mag Magerr \nSTEP23a 60111.4340 40.79975 -46.65150667 g 19.806 0.09\n\nWe have checked the Minor Planet Center and Transient Name Server, finding no previously reported solar system object or transient. We encourage follow-up observations of this source.\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg3MDQwMTA2LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.9WByuMPLSJHA4jlT3Q5b4MJnQu14ukeUKkgnjKeYh1I\n\n",

"message_text": "\nK. L. Page (U Leicester) and S. Laha (GSFC/UMBC) report on behalf of\nthe Neil Gehrels Swift Observatory Team:\n\nAt 03:51:12 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 230618A (trigger\u001175438). Swift slewed immediately to the burst.\nThe BAT on-board calculated location is\nRA, Dec 196.588, +3.306 which is\n RA(J2000) = 13h 06m 21s\n Dec(J2000) = +03d 18' 20\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including\nsystematic uncertainty). Due to a telemetry outage caused by\na recent storm in Guam, no further BAT data will be available\nuntil a ground station pass.\n\nUsing promptly downlinked data we find a bright, uncatalogued X-ray\nsource located at RA, Dec 196.60313, 3.30257 which is equivalent to:\n RA(J2000) = 13h 06m 24.75s\n Dec(J2000) = +03d 18' 09.3\"\nwith an uncertainty of 5.8 arcseconds (radius, 90% containment). This\nposition may be improved as more data are received; the latest position\nis available at https://www.swift.ac.uk/sper. No spectrum from the\npromptly downlinked event data is yet available to determine the column\ndensity.\n\nThe initial flux in the 2.5 s image was 6.46e-10 erg cm^-2 s^-1 (0.2-10\nkeV).\n\nUVOT took a finding chart exposure of nominal 150.000 seconds with the White\nfilter starting 137 seconds after the BAT trigger. No credible afterglow\ncandidate has been found in the initial data products. Data from the 2.7'x2.7'\nsub-image are not available at this time. The 8'x8' region for the list of\nsources generated on-board covers 100% of the XRT error circle. The list of\nsources is typically complete to about 18 mag. No correction has been made for\nthe expected extinction corresponding to E(B-V) of 0.025.\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.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg3MDYxMzY3LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.MQfImm3I9xu-PTD9KpzeQc0PLcalDBTT_5A7Rk4zJV8\n\n",

The\ntotal exposure time is 4.6 ks, distributed over 4 tiles; the maximum\nexposure at a single sky location was 2.0 ks. The data were collected\nbetween T0+111.3 ks and T0+140.7 ks, and are entirely in Photon\nCounting (PC) mode.\n\nThree uncatalogued X-ray sources have been detected, however none of\nthem is above the RASS limit or shows definitive signs of fading.\nTherefore, at the present time we cannot identify which, if any, is the\nafterglow.

Ambrosi (INAF-IASFPA) , M. Capalbi\n(INAF-IASFPA) report on behalf of the Swift-XRT team:\n\nWe have analysed 6.3 ks of XRT data for GRB 230618A, from 118 s to 30.0\nks after the BAT trigger. The data comprise 157 s in Windowed Timing\n(WT) mode (the first 9 s were taken while Swift was slewing) with the\nremainder in Photon Counting (PC) mode. The best available XRT position\n (using the promptly downlinked event data, the XRT-UVOT alignment and\nmatching UVOT field sources to the USNO-B1 catalogue) is RA, Dec 196.60531, 3.30238 which is equivalent to:\n\nRA (J2000): 13 06 25.27\nDec(J2000): +03 18 08.6\n\nwith an uncertainty of 1.9 arcsec (radius, 90% confidence).\n\nThe light curve can be modelled with a series of power-law decays. The\ninitial decay index is alpha=1.10 (+0.13, -0.10). At T+594 s the decay\nsteepens to an alpha of 2.90 (+0.40, -0.23) before breaking again at\nT+3047 s to a final decay with index alpha=0.29 (+0.68, -0.29).\n\nA spectrum formed from the WT mode data can be fitted with an absorbed\npower-law with a photon spectral index\tof 1.55 (+0.13, -0.12). The\nbest-fitting absorption column is 1.4 (+0.5, -0.4) x 10^21 cm^-2, in\nexcess of the Galactic value of 2.1 x 10^20 cm^-2 (Willingale et al.\n2013). The PC mode spectrum has a photon index of 1.73 (+/-0.17) and a\nbest-fitting absorption column of 2.1 (+0.7, -0.6) x 10^21 cm^-2. The\ncounts to observed (unabsorbed) 0.3-10 keV flux conversion factor\ndeduced from this spectrum is 4.1 x 10^-11 (5.2 x 10^-11) erg cm^-2\ncount^-1.\n\nA summary of the PC-mode spectrum is thus:\nTotal column:\t 2.1 (+0.7, -0.6) x 10^21 cm^-2\nGalactic foreground: 2.1 x 10^20 cm^-2\nExcess significance: 5.0 sigma\nPhoton index:\t 1.73 (+/-0.17)\n\nIf the light curve continues to decay with a power-law decay index of\n0.29, the count rate at T+24 hours will be 8.8 x 10^-3 count s^-1,\ncorresponding to an observed (unabsorbed) 0.3-10 keV flux of 3.6 x\n10^-13 (4.5 x 10^-13) erg cm^-2 s^-1.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/01175438.\n\nThis circular is an official product of the Swift-XRT team.\n\n\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg3MTAzODEwLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.TT35uyXOtBBpivrTwpu_VdJaVn6dPhg6kyLTwX_bcZk\n\n",
