//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26640 SUBJECT: LIGO/Virgo S200105ae: A subthreshold GW compact binary merger candidate DATE: 20/01/06 18:25:26 GMT FROM: Peter Shawhan at U of Maryland/LSC The LIGO Scientific Collaboration and the Virgo Collaboration report: We identified the compact binary merger candidate S200105ae in data from LIGO Livingston Observatory (L1) and Virgo Observatory (V1) at 2020-01-05 16:24:26.057 UTC (GPS time: 1262276684.057). The candidate was found by the GstLAL [1] analysis pipeline. LIGO Hanford Observatory (H1) was offline at the time. The signal-to-noise ratio (SNR) was below threshold in V1 so the candidate was treated as a single-instrument event. The false alarm rate (FAR) estimated from the L1 trigger, 7.6e-07 Hz -- or about 24 per year -- was above the threshold we normally use for issuing a public alert. However, after further offline analysis of the candidate, we believe that its significance is greater than that calculated in real-time processing. Follow-up observations may therefore be justified. The event's properties can be found at this URL: https://gracedb.ligo.org/superevents/S200105ae We cannot quantify the probability of this event being astrophysical at this time. However, if it is astrophysical, it is most consistent with being a neutron star - black hole (NSBH) event. Under this assumption, there is strong evidence for the lighter compact object having a mass < 3 solar masses (HasNS: >99%). Using the masses and spins inferred from the signal, it is possible but unlikely that the merger left matter outside the final compact object. (HasRemnant was estimated as 12% by the initial analysis, but this value is considered uncertain.) One sky map is available at this time and can be retrieved from the GraceDB event page: * bayestar.fits.gz,0, an initial localization generated by BAYESTAR [2]. No GCN notice has been issued for this candidate. For the bayestar.fits.gz sky map, the 90% credible region is 7719 deg2, dominated by the L1 antenna response. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 265 +/- 71 Mpc (a posteriori mean +/- standard deviation).

We have now issued a pair of GCN Notices (Preliminary and Initial) for this candidate in order to support users who rely on Notices for getting sky maps and scheduling observations. These Notices are identical and do not contain any updated information about the candidate; in particular, the p_astro and em_bright probabilities in the Notice are from the initial real-time processing and are not considered accurate, as explained in Circular 26640. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26643 SUBJECT: LIGO/Virgo S200105ae : no neutrino counterpart candidate in ANTARES search DATE: 20/01/06 19:52:38 GMT FROM: Thierry Pradier at ANTARES/IPHC/U of Strasbourg M. Ageron (CPPM/CNRS), B. Baret (APC/CNRS), A. Coleiro (APC/Universite de Paris), M. Colomer (APC/Universite de Paris), D. Dornic (CPPM/CNRS), A. Kouchner (APC/Universite de Paris), T. Pradier (IPHC/Universite de Strasbourg) report on behalf of the ANTARES Collaboration: Using on-line data from the ANTARES detector, we have performed a follow-up analysis of the recently reported LIGO/Virgo S200105ae subthreshold event using the 90% contour of the Initial GW_SKYMAP probability map provided by the GW interferometers (GCN#26640 ). The ANTARES visibility at the time of the alert, together with the 50% and 90% contours of the probability map are shown at http://antares.in2p3.fr/GW/S200105ae_Initial.png . Considering the location probability provided by the LIGO/Virgo collaborations, there is a 35.6% chance that the GW emitter was in the ANTARES **upgoing** field of view at the time of the alert. No up-going muon neutrino candidate events were recorded in the ANTARES sky during a +/-500s time-window centered on the time 2020-01-05 16:24:26 and in the 90% contour of the S200105ae event. The expected number of atmospheric background events in the region visible by ANTARES is 2.43e-03 in the +/- 500s time window. An extended search during +/- 1 hour gives no up-going muon neutrino coincidence. The expected number of atmospheric background events in the region visible by ANTARES is 1.75e-02 in this larger time window. ANTARES is the largest undersea neutrino detector, installed in the Mediterranean Sea, and it is primarily sensitive to neutrinos in the TeV-PeV energy range. At 10 TeV, the median angular resolution for muon neutrinos is about 0.5 degrees. In the range 1-100 TeV ANTARES has a competitive sensitivity to this position in the sky. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26644 SUBJECT: LIGO/Virgo S200105ae: No counterpart candidates in INTEGRAL SPI-ACS prompt observation DATE: 20/01/06 20:05:22 GMT FROM: Maeve Doyle at U College Dublin, Ireland Maeve Doyle, Antonio Martin-Carrillo (UCD, Dublin) V. Savchenko, C. Ferrigno (ISDC/UniGE, Switzerland) J. Rodi (IAPS-Roma, Italy) A. Coleiro (APC, France) S. Mereghetti (INAF IASF-Milano, Italy) on behalf of the INTEGRAL multi-messenger collaboration: https://www.astro.unige.ch/cdci/integral-multimessenger-collaboration Using INTEGRAL/SPI-ACS realtime data (following [1]) we have performed a search for a prompt gamma-ray counterpart of S200105ae (GCN 26640). At the time of the event (2020-01-05 16:24:26 UTC, hereafter T0), INTEGRAL was operating in nominal mode. The peak of the event localization probability was at an angle of 83 deg with respect to the spacecraft pointing axis. This orientation implies strongly suppressed (15% of optimal) response of ISGRI, strongly suppressed (35% of optimal) response of IBIS/Veto, and near-optimal (90% of optimal) response of SPI-ACS. The background within +/-300 seconds around the event was very stable (excess variance 1.1). We have performed a search for any impulsive events in INTEGRAL SPI- ACS (as described in [2]) data. We do not detect any significant counterparts and estimate a 3-sigma upper limit on the 75-2000 keV fluence of 2.2e-07 erg/cm^2 (within the 50% probability containment region of the source localization) for a burst lasting less than 1 s with a characteristic short GRB spectrum (an exponentially cut off power law with alpha=-0.5 and Ep=600 keV) occurring at any time in the interval within 300 s around T0. For a typical long GRB spectrum (Band function with alpha=-1, beta=-2.5, and Ep=300 keV), the derived peak flux upper limit is ~1.9e-07 (5.5e-08) erg/cm^2/s at 1 s (8 s) time scale in 75-2000 keV energy range. For the mean reported distance 265.0 Mpc this corresponds to the limit on the total isotropic equivalent energy in 1 s of 1.9e+48 erg for the short GRB spectrum and for a long GRB spectrum isotropic equivalent luminosity in 1 s (8 s) of 1.3e+48 erg/s (4.6e+47 erg/s) We report for completeness and in order of FAP, all excesses identified in the search region. We find 1 possibly associated excess: T-T0 | scale | S/N | luminosity ( x 1e+48 erg/s) | FAP -1.1 | 2.25 | 3.3 | 19.7 +/- 7.29 +/- 13.8 | 0.0101 6 likely background excesses: T-T0 | scale | S/N | luminosity ( x 1e+48 erg/s) | FAP -6.25 | 0.05 | 4.4 | 17.3 +/- 5.03 +/- 12.1 | 0.14 108 | 0.6 | 4.5 | 5.07 +/- 1.42 +/- 3.55 | 0.363 144 | 1.4 | 3.6 | 25.6 +/- 9.26 +/- 17.9 | 0.607 23.4 | 0.2 | 3.6 | 6.98 +/- 2.47 +/- 4.88 | 0.704 -192 | 0.6 | 4.4 | 4.94 +/- 1.42 +/- 3.45 | 0.708 -60.5 | 1.1 | 3.2 | 2.63 +/- 1.04 +/- 1.84 | 0. 866 Note that FAP estimates (especially at timescales above 2s) may be possibly further affected by enhanced non-stationary local background noise. This list excludes any excesses for which FAP is close to unity. All results quoted are preliminary. This circular is an official product of the INTEGRAL Multi-Messenger team.

Veres (UAH) reports on behalf of the Fermi-GBM Team and the GBM-LIGO/Virgo group For S200105ae and using the latest BAYESTAR skymap, Fermi-GBM was observing 82.3% of the localization probability at event time. There was no Fermi-GBM onboard trigger around the event time of the LIGO/Virgo detection of GW trigger S200105ae (GCN Circ. 26640). An automated, blind search for short gamma-ray bursts below the onboard triggering threshold in Fermi-GBM also identified no counterpart candidates. The GBM targeted search, the most sensitive, coherent search for GRB-like signals, was run from +/-30 s around merger time, and also identified no counterpart candidates. Part of the LVC localization region is behind the Earth for Fermi, located at RA=255.8, Dec=22.4 with a radius of 67.4 degrees. We therefore set upper limits on impulsive gamma-ray emission for the LVC localization region visible to Fermi at merger time. Using the representative soft, normal, and hard GRB-like templates described in arXiv:1612.02395, we set the following 3 sigma flux upper limits over 10-1000 keV, weighted by GW localization probability (in units of 10^-7 erg/s/cm^2): Timescale Soft Normal Hard ------------------------------------ 0.128 s: 4.0 6.3 11 1.024 s: 1.1 1.8 4.4 8.192 s: 0.40 0.63 1.3 Assuming the median luminosity distance of 265 Mpc from the GW detection, we estimate the following intrinsic luminosity upper limits over the 1 keV-10 MeV energy range (in units of 10^48 erg/s): Timescale Soft Normal Hard ------------------------------------ 0.128s: 5.1 7.5 21 1.024s: 1.4 2.1 8.6 8.192s: 0.51 0.75 2.5 //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26646 SUBJECT: LIGO/Virgo S200105ae: Global MASTER-Net observations report DATE: 20/01/06 20:42:19 GMT FROM: Vladimir Lipunov at Moscow State U/Krylov Obs V.

Troja (NASA/GSFC/UMCP) report on behalf of the Swift team: We report the search results in the BAT data within T0 +/- 100 s of the LVC event S200105ae (LIGO/VIRGO Collaboration GCN Circ. 26557), where T0 is the LVC trigger time (2020-01-05T16:24:53.057 UTC). The center of the BAT field of view (FOV) at T0 is RA = 206.337 deg, DEC = 41.706 deg, and the roll angle is 103.682 deg. The BAT FOV (>10% partial coding) covers 10.35% of the integrated LVC localization probability. Note that the sensitivity in the BAT FOV changes with the partial coding fraction. Please see the BAT FOV figure in the summary page (link below) for the specific location of the LVC region relative to the BAT FOV. Within T0 +/- 100 s, no significant astrophysical detections (signal-to-noise ratio >~ 5 sigma) are found in the BAT raw light curves with time bins of 64 ms, 1 s, and 1.6 s. The pulse and the dip seen at ~T0+50 s is due to onboard calibration process during spacecraft slews. Assuming an on-axis (100% coded) short GRB with a typical spectrum in the BAT energy range (i.e., a simple power-law model with a power-law index of -1.32, Lien & Sakamoto et al. 2016), the 5-sigma upper limit in the 1-s binned light curve corresponds to a flux upper limit (15-350 keV) of ~ 1.60 x 10^-7 erg/s/cm^2. Assuming a luminosity of ~ 2 x 10^47 erg/s (similar to GW170817) and an average Epeak of ~ 400 keV for short GRBs (Bhat et al. 2016), this flux upper limit corresponds to a distance of ~ 56.80 Mpc. No event data are available within T0 +/- 100 s. BAT retains decreased, but significant, sensitivity to rate increases for gamma-ray events outside of its FOV. About 7.88% of the integrated LVC localization probability was outside of the BAT FOV but above the Earth's limb from Swift's location, and the corresponding flux upper limits for this region are within roughly an order of magnitude higher than those within the FOV.

At the time of the trigger the HAWC local zenith was oriented towards (RA, Dec) = (253.3 deg, 19.0 deg). 14% of the GW candidate sky location probability fell within our observable field of view (0-45 deg zenith angle). We performed a search for a short timescale emission using 6 sliding time windows (dt = 0.3s, 1s, 3s, 10s, 30s and 100s), shifted forward in time by 20% of their width. We searched the 95% probability containment area in a timescale-dependent time period, from t0-5dt to t0+10dt, where t0 is the time of the GW trigger. No significant gamma-ray detection above the background was observed. The sensitivity of this analysis is greatly dependent on zenith angle, ranging from 0 deg to 45 deg for the area searched in this analysis. The 5sigma detection sensitivity to a 1s (100s) burst in the 80-800GeV energy range goes from 1.2e-6 erg/cm^2 to 1.1e-4 erg/cm^2 (6.4e-6 erg/cm^2 to 5.0e-4 erg/cm^2), depending on the zenith angle. HAWC is a TeV gamma ray water Cherenkov array located in the state of Puebla, Mexico. It is sensitive to the energy range ~0.1-100TeV, and monitors 2/3 of the sky every day with an instantaneous field-of-view of ~2 sr. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26651 SUBJECT: LIGO/Virgo S200105ae: Coverage and upper limits from MAXI/GSC observations DATE: 20/01/07 03:43:48 GMT FROM: Motoko Serino at RIKEN/MAXI S.

At the trigger time of S200105ae, the high-voltage of MAXI/GSC was off, and it was turned on at T0+93 sec (+1.6 min). The first one-orbit (92 min) scan observation with GSC after the event covered 82% of the 90% credible region of the bayestar skymap from 16:25:59 to 17:32:25 UTC (T0+93 to T0+4079 sec). No significant new source was found in the region in the one-orbit scan observation. A typical 1-sigma averaged upper limit obtained in one scan observation is 20 mCrab at 2-20 keV.

Shenoy (IITB), Aarthy E. (PRL), V. Bhalerao (IITB), D. Bhattacharya (IUCAA), A. R. Rao (TIFR), S. Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration: We have carried a search for X-ray candidates in Astrosat CZTI data in a 100 sec window around the trigger time of the subthreshold GW compact binary merger candidate S200105ae (UTC 2020-01-05 16:24:26.000, GraceDB event). CZTI is a coded aperture mask instrument that has considerable effective area for about 29% of the entire sky, but is also sensitive to brighter transients from the entire sky. At the time of merger, Astrosat's nominal pointing is RA,DEC = 22:07:55.2,31:23:52.1 (331.9800,31.3978), which is ~82 deg away from the maximum probability location, which severely reduces the effective area of CZTI. At the time of merger event, the Earth-satellite-transient angle corresponding to maximum probability location is ~109 deg and hence is not occulted by Earth in satellite's frame. In a time interval of 100 sec around the event, the region of the sky map (LVC GCN 26640) which is not occulted by Earth in the satellite's frame has a cumulative probability of 0.89 (89%). CZTI data were de-trended to remove orbit-wise background variation. We then searched data from the four independent, identical quadrants to look for coincident spikes in the count rates. Searches were undertaken by binning the data in 0.1s, 1s, and 10s respectively. Statistical fluctuations in background count rates were estimated by using data from 10 (+-5) neighbouring orbits. We selected confidence levels such that the probability of a false trigger in a 1000 sec window is 10^-4. We do not find any evidence for any hard X-ray transient in this window, in the CZTI energy range of 20-200 keV. We use a detailed mass model of the satellite to calculate the direction-dependent instrument response for points in the visible sky. We then assume the source is modelled as a power law with photon index alpha = -1, and convert our count rate upper limits to direction-dependent flux limits. We obtain the following upper limits for source flux in the 20-200 keV band by taking a probability weighted mean over the visible sky: 0.1 s: flux limit= 1.83e-05 ergs/cm^2/s; fluence limit = 1.83e-06 ergs/cm^2 1.0 s: flux limit= 5.59e-06 ergs/cm^2/s; fluence limit = 5.59e-06 ergs/cm^2 10.0 s: flux limit= 1.00e-06 ergs/cm^2/s; fluence limit = 1.00e-05 ergs/cm^2 CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC and PRL.

The tiling was optimally determined and triggered using the GROWTH Target of Opportunity marshal (Coughlin et al. 2019a, Kasliwal et al. 2019b). We started obtaining target-of-opportunity observations in the g-band and r-band beginning at 2020-01-07 01:54 UT. Combining triggered 180s and serendipitous 30s observations, we covered 45.1% of the enclosed probability with a median depth of 19.5 mag (due to poor seeing conditions and proximity to the moon). The images were processed in real-time through the ZTF reduction and image subtraction pipelines at IPAC to search for potential counterparts (Masci et al. 2019). Alert filtering and follow-up coordination was undertaken by the GROWTH Marshal system (Kasliwal et al. 2019). The ZTF alert stream was also queried using the Kowalski infrastructure (Duev et al., 2019) and with AMPEL (Nordin et al. 2019). No candidates of interest have been identified thus far.

Marrocchesi (U of Siena), and the CALET collaboration: The CALET Gamma-ray Burst Monitor (CGBM) was operating at the trigger time of S200105ae T0 = 2020-01-05 16:24:26.057 UT (The LIGO Scientific Collaboration and Virgo Collaboration, GCN Circ.26640). No CGBM on-board trigger occurred around the event time. Based on the LIGO-Virgo localization sky map, the summed LIGO probabilities inside the CGBM HXM (7 - 3000 keV) and SGM (40 keV - 28 MeV) fields of view are 71 % and 82 %, respectively (and 84 % credible region of the initial sky map was above the horizon). The HXM and SGM fields of view were centered at RA = 42.4 deg, Dec =-23.7 deg and RA = 50.5 deg, Dec = -30.6 deg at T0, respectively. CGBM high voltages were turning on around T0-60 sec. Based on the analysis of the light curve data with 0.125 sec time resolution from T0-50 sec to T0+60 sec, we found no significant excess around the trigger time in either the HXM or the SGM data. The CALET Calorimeter (CAL) was operating in the high energy trigger mode at the trigger time of S200105ae. Using the CAL data, we have searched for gamma-ray events in the 10-100 GeV band from -60 sec to +60 sec from the GW trigger time and found no candidates in the overwrap region with the LIGO-Virgo high probability localization region. The 90% upper limit of CAL is 6.5x10^-6 erg/cm^2/s (10-100 GeV) when the summed LIGO-Virgo probability reaches 60%. The CAL FOV was centered at RA= 50.6 deg, DEC= -30.6 deg at T0. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26673 SUBJECT: LIGO/Virgo S200105ae: Candidates from the Zwicky Transient Facility DATE: 20/01/08 19:46:30 GMT FROM: Robert Stein at DESY R.

The tiling was optimally determined and triggered using the GROWTH Target of Opportunity marshal (Coughlin et al. 2019a, Kasliwal et al. 2019b). Last night, we triggered target-of-opportunity observations in the g-band and r-band beginning at 2020-01-08 05:00 UT. With our triggered 180s observations, we covered 17.7% of the enclosed probability with a median depth of 20.2 mag. Based on the total triggered and serendipituous coverage in the last three nights since merger time, we covered 51.7% of the enclosed probability with a median depth of 19.7 mag. The images were processed in real-time through the ZTF reduction and image subtraction pipelines at IPAC to search for potential counterparts (Masci et al. 2019).

Parameter estimation has been performed using LALInference [1] and a new sky map, LALInference.fits.gz,0, distributed via GCN Notice, is available for retrieval from the GraceDB event page: https://gracedb.ligo.org/superevents/S200105ae The preferred sky map at this time is LALInference.fits.gz,0. For the LALInference.fits.gz,0 sky map, the 90% credible region is 7373 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 283 +/- 74 Mpc (a posteriori mean +/- standard deviation). Based on posterior support from parameter estimation [1], under the assumption that the candidate S200105ae is astrophysical in origin, the probability that the lighter compact object has a mass < 3 solar masses (HasNS) is 98%. Using the masses and spins inferred from the signal, the probability of matter outside the final compact object (HasRemnant) is <1%. There is no change to our assessment of the significance of the candidate. As noted in the previous Circulars, our examination of the data indicates that the signal has greater significance than what was calculated in real-time processing (and is still contained in the GCN Notice), sufficient to warrant a public alert.

GCNC 26686) within the error area of the GW event S200105ae (LVC, GCNC 26640), we obtained an optical spectrum covering the range 3700-7400 A with the 10.4m GTC telescope equipped with OSIRIS in La Palma (Spain) on Jan 10, 06:53 UT. For AT2020oo/Gaia20add, a magnitude r'= 17.56 +/- 0.02 at 06:49 UT is derived. The GTC spectrum is consistent with a SN Ia at redshift z = 0.0486 +/- 0.0005 (based on the emission lines of the host galaxy). Therefore we consider that AT2020oo/Gaia20add is unrelated to the S200105ae GW alert. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26702 SUBJECT: LIGO/Virgo S200105ae: AT2020pp and AT2020py 10.4m GTC spectroscopy DATE: 20/01/11 11:34:38 GMT FROM: Alberto J.

For AT2020pp/ZTF20aaervoa, the GTC spectrum is consistent with a SN IIP at about 3 days after maximum at redshift z = 0.046 +/- 0.003, consistent with the redshift of the host galaxy derived from the emission lines (z = 0.0448 +/- 0.0005). For AT2020py/ZTF20aaerxsd, the GTC spectrum is consistent with a SN Ia  at about 3 days after maximum at redshift z = 0.055 +- 0.005, consistent with the redshift of the host galaxy derived from the emission lines (z =  0.0533 +/- 0.0005). Therefore we consider that neither AT2020pp/ZTF20aaervoa nor AT2020py/ZTF20aaerxsd are related to the S200105ae GW alert.

For AT2020pq/ZTF20aaervyn, the GTC spectrum is consistent with a SN Ia close to maximum, at redshift z = 0.112 +/- 0.004, consistent with the redshift of the host galaxy derived from the emission lines (z = 0.1146 +/- 0.0005). For AT2020ps/ZTF20aaerqbx, the GTC spectrum is consistent with a SN IIp about 5 days prior to maximum at redshift z = 0.098 +/- 0.016, consistent with the redshift of the host galaxy derived from the emission lines (z = 0.0780 +/- 0.0005). For AT2020pv/ZTF20aaertpj, the GTC spectrum is consistent with a SN Ib close to maximum at redshift z = 0.026 +/- 0.006, consistent with the redshift of the host galaxy derived from the emission lines (z = 0.0280 ± 0.0005). Therefore we consider that AT2020pq/ZTF20aaervyn, AT2020ps/ZTF20aaerqbx and AT2020pv/ZTF20aaertpj are unrelated to the S200105ae GW alert.

Kasliwal (Caltech), Simeon Reusch (DESY), Robert Stein (DESY), Matthew Graham (Caltech), Jesper Sollerman (OKC) on behalf of the Zwicky Transient Facility (ZTF) and Global Relay of Observatories Watching Transients Happen (GROWTH) collaborations We serendipitously observed the localization region of the gravitational wave trigger S200105ae (LVC, GCN #26640) with the Palomar 48-inch telescope equipped with the 47 square degree Zwicky Transient Facility camera (ZTF, Bellm et al. 2019, Graham et al. 2019) during the regular ZTF survey (i.e., without triggering further ToO observations in addition to those described in Anand et al, GCN #26662). The images were processed in real-time through the ZTF reduction and image subtraction pipelines at IPAC (Masci et al. 2019). We queried the ZTF alert stream using Kowalski (Duev et al., 2019) and AMPEL (Nordin et al., 2019), requiring at least 2 detections separated by at least 15 minutes to select against moving objects. Furthermore, we cross-matched our candidates with the Minor Planet Center to flag known asteroids. We require that no spatially coincident ZTF alert has been issued before the detection time of S200105ae. New candidates were found within the 95% probability contour of S200105ae, in addition to those reported by Stein et al. (GCN #26673).

Ridnaia, S. Golenetskii, R.Aptekar, D. Frederiks, M. Ulanov, D. Svinkin, A. Tsvetkova, A. Lysenko, and T. Cline, on behalf of the Konus-Wind team, report: Konus-Wind (KW) was observing the whole sky at the time of the LIGO/Virgo event S200105ae (2020-01-05 16:24:26.057 UTC, hereafter T0; LIGO/Virgo Collaboration GCN Circ. 26640). No triggered KW GRBs happened ~4 days before and ~6 days after T0. The closest waiting-mode GRB was observed ~5 hours after T0. Using waiting-mode data within the interval T0 +/- 100 s, we found no significant (> 5 sigma) excess over the background in both KW detectors on temporal scales from 2.944 s to 100 s. We estimate an upper limit (90% conf.) on the 20 - 1500 keV fluence to 9.2x10^-7 erg/cm^2 for a burst lasting less than 2.944 s and having a typical KW short GRB spectrum (an exponentially cut off power law with alpha =-0.5 and Ep=500 keV). For a typical long GRB spectrum (the Band function with alpha=-1, beta=-2.5, and Ep=300 keV), the corresponding limiting peak flux is 2.5x10^-7 erg/cm^2/s (20 - 1500 keV, 2.944 s scale). All the quoted values are preliminary.
