  A co-orbital asteroid shares the orbit of a secondary body about its primary.
Though more commonly encountered as an asteroid that shares a planet's orbit
around the Sun, a co-orbital asteroid could similarly share the orbit of the
Moon around the Earth. Though such asteroids would be close to Earth and so
relatively bright, their rapid on-sky motion is such that they might escape
detection by near-Earth asteroid surveys. The discovery of such lunar
co-orbital asteroids (which we will refer to generically here as Lunar Trojans
or LTs) would advance our understanding of inner Solar System orbital dynamics
and would provide research opportunities for the growing number of missions
slated for cislunar space. No LT asteroids are currently known and the last
published survey dedicated to these asteroids was conducted nearly 40 years
ago. It has been theoretically determined that orbits near the Earth-Moon L4
and L5 points could survive for several million years. Although this timescale
is shorter than the lifetime of the Solar System, it introduces the possibility
of the temporary capture of asteroids into the LT state. This project aims to
observationally evaluate the population of LTs with modern techniques. Using
four small ground-based telescopes from the iTelescope network, $8340\;deg^2$
on the sky were surveyed down to $15^{th}$ magnitude. Though one fast-moving
near-Earth object was detected, no LTs were observed. We deduce an upper limit
of $\lesssim 5$ LTs with $H<26$.
