Andrew C. Collazzi (NASA/ORAU) reports on behalf of the Fermi GBM Team: "At 21:44:09.64 UT on 15 July 2013, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 130715A (trigger 395617452 / 130715.906). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 287.4, Dec = -31.1 (J2000 degrees, equivalent to J2000 19h 9m, -31d 3'), with a statistical uncertainty of 1.0 degree (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 96 degrees. The trigger occurred during a nadir pointing maneuver of the Fermi spacecraft. The GBM light curve shows single continuous emission with a duration (T90) of about 48 s (50-300 keV). The peak flux during this interval is 7.75 +/- 0.31 ph/s/cm^2. The time-averaged spectrum from T0+0.00 to T0+61.44 s is best fit by a Band function with Epeak = 314.60 +/- 12.40, alpha = -0.58 +/- 0.03, beta = -2.44 +/- 0.12. The fluence (10-1000 keV) in this time interval is (4.7 +/- 0.061)E-05 erg/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
