Abrupt changes of the Earth's rotation speed in ancient times
Abstract
In our recent work using ancient solar eclipse records we showed that the Earth’s rotation rate changed abruptly in about AD 900 (Sôma and Tanikawa 2005). We show here that more abrupt changes in the Earth’s rate of rotation occurred in about AD 500.
