The region around 13h in Right Ascension, containing most of the probability for the LIGO CBC
candidate G194575 reported by Singer et al. GCN 18442, was observed by Fermi GBM during
the GW event. The region around 01h was occulted by the Earth.
A search of the GBM Time-Tagged Event data between 8 keV and 40 MeV from 64 s before to
82 s after the CBC candidate event revealed no significant emission on search timescales in
factors of 2 from 64 ms to 2.048 s.
