Preprint Suggests Lunar Tides Could Affect Clock Frequencies on Moon

A new preprint on arXiv investigates how the Moon's tidal response might cause variations in clock frequencies on its surface. As lunar clock performance improves, the instability and uncertainty of fractional frequency shifts are becoming comparable to those induced by tidal forces. The study analyzes these shifts, considering the Moon's elliptical orbit, but notes these are preliminary, un-peer-reviewed findings.
