//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 16576 SUBJECT: GRB 140710B: a long GRB detected with INTEGRAL DATE: 14/07/10 23:59:31 GMT FROM: Diego Gotz at CEA D.Gotz (CEA, Saclay), S.Mereghetti (IASF-Milano), C.Ferrigno, E.Bozzo, D. Malishev (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: a gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 21:37:30 UT of July 10, 2014. Due to a S/W maintenance problem at ISDC no refined coordinates can currently be computed. So the automatic coordinates should be considered at this time. Refined coordinates will be posted as soon as the attitude files will be available again. The automatic coordinates are: R.A.= 204.657 deg DEC.= -58.5854 deg with an uncertainty of 2.8 arcmin (90% c.l.). A preliminary analysis gives a peak flux of about 1.2 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 1e-6 erg/cm2. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html [GCN OPS NOTE(10jul14): Per author's request, the "July 11" date in the first sentence was corrected to "Jul10.] //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 16578 SUBJECT: GRB 140710B: improved INTEGRAL position DATE: 14/07/11 12:10:13 GMT FROM: Diego Gotz at CEA D.Gotz (CEA, Saclay), S.Mereghetti (IASF-Milano), C.Ferrigno, E.Bozzo, (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: We derived for the INTEGRAL GRB 140710B (Gotz et al., GCN 16576) a refined position and a reduced error box using the updated attitude information and the IBIS/ISGRI data. The refined coordinates are: R.A.= 204.6457 deg Dec.= -58.5913 deg with an uncertainty of 1.7 arcmin (90% c.l.). We note that this refined position is fully consistent with the automatic one. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 16579 SUBJECT: GRB 140710B: Fermi GBM detection DATE: 14/07/11 20:09:53 GMT FROM: Eric Burns at U of Alabama E. Burns (UAH) reports on behalf of the Fermi GBM Team: "At 21:37:37.94 UT on 10 July 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140710B (trigger 426721060 / 140710901). which was also detected by INTEGRAL IBIS/ISGRI (Gotz et al., GCN 16576). The GBM on-ground location is consistent with the refined INTEGRAL position (Gotz et al., GCN 16578). The angle from the Fermi LAT boresight is 79 degrees. The GBM light curve shows multiple peaks with a duration (T90) of about 30.7 s (50-300 keV). The time-averaged spectrum from T0-56 s to T0+68 s is best fit by a simple power law function with index -1.9 +/- 0.1. The event fluence (10-1000 keV) in this time interval is (2.3 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0-1.2s in the 10-1000 keV band is 2.7 +/- 0.5 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
