K. ; Liu, Ciyuan Abstract Fifty-eight records of naked-eye observations of occultations of the planets by the moon chosen from the Chinese dynastic histories are studied. These records cover the period from 68 B.C. to 575 A.D. The observations are compared to topocentric ephemerides computed using Bretagnon's planetary theories VSOP82 and the Chapront-Touze lunar theory ELP2000-85. Overall, the check on the change in the rotation rate is very weak, but it represents the limit of what can be done with known, untimed occultation records.
