With more than 9 years of Pass 8 LAT data, we updated the gamma-ray spectral properties and the LAT localization of the gamma-ray source. While the binary lies outside the cataloged 95% error ellipse, the optimized LAT ellipse is 0.1 degrees closer and encloses the binary. The system is likely spectrally hard in X-rays (photon index ~ 1.4) with orbital modulations detected in optical, UV, and possibly X-rays.
