Near-Earth Asteroid Detection with the ATLAS Survey

The Asteroid Terrestrial-impact Last Alert System (ATLAS) is a NASA-funded, all-sky, robotic telescope survey developed by the University of Hawaii to efficiently detect hazardous near- Earth asteroids (NEAs) and other moving objects. Operated by the University of Hawaii in conjunction with collaborators in the UK and elsewhere around the world, ATLAS employs four wide-field telescopes to survey the entire visible night sky to a limiting dark-time V magnitude of 19.7 with a cadence of roughly two days. Two of the ATLAS telescopes, located in Hawaii, have been in operation since 2017. Two additional units have been operational in Chile and South Africa since 2022. A fifth unit, currently under construction in the Canary Islands, will join the ATLAS survey in the near future. In this presentation I will provide a brief overview of the current ATLAS survey system, its asteroid detection ability, and the ongoing effort to optimize our system for the newly added telescopes.
