  We reported a photon detection at the arrival time of the gravitational wave
on December 26th, 2015. According to the LIGO-Virgo collaboration, the
gravitational wave was produced by the merging process of the two black holes.
The merged time was determined at 03:38:53.6 UT on December 26th. At
03:38:54.05 GPS time, one of the detectors of SEDA-FIB on board the
International Space Station (ISS) detected a photon, arriving from the
direction of Corona Australis near the Galactic Bulge (GB). The energy of the
photon was about (35+-7) MeV. A 3.0 sigma level detection of the photon is
discussed.
