The U.S. Naval Observatory (USNO), in collaboration with Paris Observatory (OP), is conducting the Fundamental Reference AGN Monitoring Experiment, or FRAMEx. FRAMEx will use USNOs and OPs in-house observing assets in the radio, infrared (IR) and visible, as well as other ground- and space-based telescopes (e.g., in the X-ray) that we can access for these purposes, to observe and monitor current and candidate Reference Frame Objects (RFOs) -- consisting of Active Galactic Nuclei (AGN) -- as well as representative AGN, in order to better understand astrometric and photometric variability at multiple timescales. FRAMEx will improve the selection of RFOs as well as provide significant new data to the AGN research community. This paper describes the FRAMEx objectives, specific areas of investigation, and the initial data collection campaigns.
