Roberts (UCD)\nreport on behalf of the Fermi GBM Team:\n\n\"At 05:00:34.23 UT on 23 June 2016, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 160623A (trigger 488350838 / 160623209 ),\nwhich was also detected by the LAT (G. Vianello et al. 2016, GCN 19553)\nand Konus-Wind (D. Frederiks et al. 2016, GCN 19554).\nThe GBM on-ground location is consistent with the LAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 83\ndegrees.\n\nThe GRB was occulted by the Earth for a large part of its duration, and\nthe GBM trigger occurred ~50 s after the start of the GRB based on\nthe Konus-Wind lightcurve.\nThe GBM light curve consists of a single peak with a duration of about 50 s.\nThe time-averaged spectrum from T0-4.9 s to T0+32.8 s is\nbest fit by a power law function.  The power law index is -1.60 +/- 0.04.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.598 +/- 0.369)E-06 erg/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
