Current status of the facility instruments at the Large Binocular Telescope Observatory

We present an overview of the current status of facility instruments at the Large Binocular Telescope (LBT). These include Optical and Near-Infrared instruments: the prime-focus optical Large Binocular Cameras (LBCs); the optical Multi-Object Double Spectrograph (MODS); and the LBT Near-IR Spectroscopic Utility with Camera Instruments (LUCIs). Each side of the telescope contains one of the aforementioned instruments. We detail the recent move to “all binocular all the time” science operations, including the use of multi-mode Adaptive Optics with the LUCIs (diffraction limited over a 30" x 30" field of view or enhanced seeing over a 4' x 4' field of view). Binocular science has three configurations: Duplex mode, with identical configurations on both sides, providing an effective collecting area of 11.9 meters; Fraternal Fraternal Twin or Mixed mode (same instruments with different setups or different instruments on each side, respectively), which is effectively two 8.4 meter telescopes; or interferometry with a 22.6 meter baseline.
