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.

[GCN OPS NOTE(26oct15):  In the FROM-line the SB was replaced with VC.
SB manually processed the submission due to problems with VC's entry
in the vetting list.  The record has now been corrected.]

[GCN OPS NOTE(15jun16):  If you are looking for the P.Evans circ 18448
("GRB 151022A: Swift-XRT refined Analysis"), please note that the ID
for that circular has been changed to "18448a".]
