Constraining ΔT from Babylonian lunar appulse and occultation observations

Year: 2017
Type: article
Abstract: We examine in detail 15 Babylonian observations of lunar appulses and occultations made between 80 and 419 BC for the purpose of setting useful limits on Earth's clock error, as quantified by $Δ$T, the difference between Terrestrial Time and Universal time. Our results are generally in agreement with reconstructions of $Δ$T using untimed solar eclipse observations from the same period. We suggest a revised version of the simple quadratic fit to $Δ$T in light of the new results.
