X-RAY/UV/OPTICAL AGN MONITORING SHOWS CONSISTENT BEHAVIOR WITHIN THE UV/OPTICAL BUT A DISCONNECT BETWEEN X-RAY AND UV/OPTICAL BROADBAND FLUX VARIATIONS THAT CHALLENGES THE STANDARD REPROCESSING MODEL. MRK 876 LIES IN THE TESS CONTINUOUS VIEWNG ZONE PROVIDING A HIGH S/N LIGHT CURVE SAMPLED EVERY 30 MINUTES FOR ~1 YEAR. DURING THIS PERIOD WE WILL OBTAIN SIMULTANEOUS MONITORING FROM THE GROUND (APPROVED) AND SWIFT (APPROVED) BUT SWIFT ONLY PROVIDES A LOW S/N X-RAY LIGHT CURVE. AS NICER IS A FACTOR OF ~20 MORE SENSITIVE IT ALLOWS MONITORING OF INDIVIDUAL COMPONENTS IN THE COMPLEX X-RAY SPECTRUM. BY CORRELATING THESE COMPONENTS (INSTEAD OF BROADBAND X-RAY FLUXES) WITH THE UV/OPTICAL NICER CAN BREAK THIS DEGENERACY AND ALLOW US TO DETERMINE WHICH X-RAY COMPONENT DRIVES THE DISK VARIABILITY.
