TITLE: GCN CIRCULAR NUMBER: 15751 SUBJECT: GRB 140118A: Fermi GBM observation DATE: 14/01/18 15:47:14 GMT FROM: Shaolin Xiong at UAH Shaolin Xiong (UAH) reports on behalf of the Fermi GBM Team: "At 01:32:07.85 UT on 18 January 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140118A (trigger 411701530 / 140118064), which was also detected by the Swift/BAT (Krimm et al., GCN 15748; Lien et al., GCN 15750). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 90 degrees. The GBM light curve consists of two separate pulses with a duration (T90) of about 92 s (50-300 keV). The time-averaged spectrum from T0-74 s to T0+23 s is adequately fit by a simple power law function with index -1.89 +/- 0.05. The event fluence (10-1000 keV) in this time interval is (6.0 +/- 0.4)E-6 erg/cm^2. The 1-sec peak photon flux measured starting from T0-2.05 s in the 10-1000 keV band is 2.5 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
