  We propose a suite of telescopes be deployed as part of the Artemis III
human-crewed expedition to the lunar south pole, able to collect wide-field
simultaneous far-ultraviolet (UV), near-UV, and optical band images with a fast
cadence (10 seconds) of a single part of the sky for several hours
continuously. Wide-field, high-cadence monitoring in the optical regime has
provided new scientific breakthroughs in the fields of exoplanets, stellar
astrophysics, and astronomical transients. Similar observations cannot be made
in the UV from within Earth's atmosphere, but are possible from the Moon's
surface. The proposed observations will enable studies of atmospheric escape
from close-in giant exoplanets, exoplanet magnetospheres, the physics of
stellar flare formation, the impact of stellar flares on exoplanet
habitability, the internal stellar structure of hot, compact stars, and the
early-time evolution of supernovae and novae to better understand their
progenitors and formation mechanisms.
