Title: Properties of the Patroclus-Menoetius Trojan binary from mutual events

Abstract: We propose to observe the mutual events between the two members of the binary Trojan asteroid Patroclus-Menoetius with LCO imaging to constrain their orbit, which will affect design decisions for NASA's Lucy mission to the Jupiter Trojans, and to study their sizes and surface properties. During their mutual event season, Patroclus and Menoetius take turns eclipsing or occulting one another every 2.14 days. Mutual events can improve orbits, constrain limb-darkening, reveal photometric properties, and map heterogeneities. The Patroclus- Menoetius mutual event season occurs twice every 12-year orbit, and the season in 2017-2019 is the last one that can affect the Lucy design.
