TITLE: GCN CIRCULAR NUMBER: 14962 SUBJECT: GRB 130701B: Fermi GBM detection DATE: 13/07/01 22:11:12 GMT FROM: Veronique Pelassa at UAH V. Pelassa (UAH) reports on behalf of the Fermi GBM Team: "At 01:27:06.27 UT on July 1st 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 130701B (trigger 394334829 / 130701060). The on-ground calculated location, using the GBM trigger data, is RA = 97.8, DEC = -60.1 (J2000 degrees, equivalent to +06h 31m, -60d 07'), with an uncertainty of 1.00 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 132 degrees. The GBM light curve consists of a single pulse with a duration (T90) of about 20 s (50-300 keV). The time-averaged spectrum from T0-2.048 s to T0+12.288 s best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.04 +/- 0.04 and the cutoff energy, parameterized as Epeak, is 564 +/- 55 keV (Castor statistics 599.92 for 492 d.o.f.). The event fluence (10-1000 keV) in this time interval is (1.28 +/- 0.03)E-05 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0+3.52 s in the 10-1000 keV band is 10.5 +/- 0.4 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
