//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 14903 SUBJECT: GRB 130614A: Fermi GBM detection DATE: 13/06/15 19:48:43 GMT FROM: Shaolin Xiong at UAH Shaolin Xiong (UAH) reports on behalf of the Fermi GBM Team: "At 23:56:09.74 UT on 14 June 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 130614A (trigger 392946972 / 130614997). High peak flux from the GRB caused GBM to issue a repoint request that reoriented the satellite to place the GRB near the LAT boresight for 2.5 hours, subject to Earth limb contraints. The on-ground calculated location, using the GBM trigger data, is RA = 324.18, DEC = -33.89 (J2000 degrees, equivalent to 21 h 36 m, -33 d 53 '), with an uncertainty of 1.2 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 17 degrees. The GBM light curve consists of a 'FRED' shape pulse with a duration (T90) of about 9.3 s (50-300 keV). The time-averaged spectrum from T0 s to T0+9.4 s is well fit by a power law function with an exponential high-energy cutoff. The power law index is -1.45 +/- 0.04 and the cutoff energy, parameterized as Epeak, is 101 +/- 5 keV. The event fluence (10-1000 keV) in this time interval is (6.1 +/- 0.2)E-6 erg/cm^2. The 1-sec peak photon flux measured starting from T0+0.19 s in the 10-1000 keV band is 20.7 +/- 0.4 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog." //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 14918 SUBJECT: GRB 130614A: Suzaku WAM observation of the prompt emission DATE: 13/06/22 11:06:17 GMT FROM: Makoto Tashiro at Saitama U/Swift S.

Nakazawa, K. Makishima (Univ. of Tokyo) on behalf of the Suzaku WAM team, report: The short GRB 130614A (Xiong, GCN 14903) was detected by the the Suzaku Wide-band All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV at 23:56:9.064 UT (=T0). The observed light curve shows a single FRED-like peak starting at T0-1 s,ending at T0+9 s with a duration (T90) of about 4.9 seconds. The fluence in 100 - 1000 keV was 3.08(+0.34/-0.31)*10^-6 erg/cm^2. The 1-s peak flux measured from T0+1s was 2.41 (+0.35/-2.9) photons/cm^2/s in the same energy range. Preliminary result shows that the time-averaged spectrum from T0-1 s to T0+9 s is well fitted by a single power-law with a photon index of 2.42 (+0.28/-0.24) (chi^2/d.o.f = 17.6/17).
