Integrating from 2017-02-27 UT 03 00 00 to 2017-03-01 UT 03 00 00 (MJD 57811.125 - 57813.125), a preliminary multi-source likelihood analysis detects a gamma-ray flux F( > 100 MeV) = (3 +/- 1) x 10^-6 photons/cm^2/s with a detection significance near 4 sigma.Request for ObservationsBinaryBlack HoleTransienthttp://adsabs.harvard.edu/abs/2017ATel10138....1P2017ATel10138....1P
