TITLE: GCN CIRCULAR NUMBER: 19026 SUBJECT: GRB 160220A: Fermi GBM observation DATE: 16/02/20 07:21:32 GMT FROM: C. Michelle Hui at MSFC/Fermi-GBM C. M. Hui (NASA/MSFC) and E. Burns (UAH) report on behalf of the Fermi GBM Team: "At 01:25:26.968 UT on 20 February 2016, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 160220A (trigger 477624330 / 160220059), which was also detected by the Swift/BAT (Lien et al. 2016, GCN 19023). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight at the GBM trigger time is 46 degrees. The GBM light curve shows a single peak with a duration (T90) of about 9 s (50-300 keV). The time-averaged spectrum from T0-3.072 s to T0+9.216 s is best fit by a simple power law function with index -1.5 +/- 0.1. The event fluence (10-1000 keV) in this time interval is (1.2 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+2.43 s in the 10-1000 keV band is 1.7 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
