The untargeted ground-based search of GBM\ndata for short-duration GRBs (Briggs et al., in prep) found no candidates\nclose in time to G288732.\n\nThe targeted search of the GBM data ([1], [2]) also did not find a\nsignificant gamma-ray signal. This search processes time scales of 0.256 to\n8.192 s within 30 s of the LIGO event. No interesting gamma-ray candidate\nwas found within this time window.\n\nFurther analysis and upper limits will be reported later.\n\n\n[1] L. Blackburn et al. 2015, ApjS 217, 8\n[2] A.
