Overview
This entry records the occurrence of a major lunar standstill in 2024 and its relevance to archaeoastronomical studies of Stonehenge. The focus is limited to the astronomical event and the monument’s known alignments. Major Lunar Standstill A major lunar standstill occurs approximately every 18.6 years. During this period, the Moon reaches its most northerly and southerly rising and setting positions on the horizon due to the combined inclination of the lunar orbit and the tilt of Earth’s axis. The result is a wider range of lunar azimuths than in typical years. In 2024, one of the southernmost moonrises associated with this cycle is observable. Stonehenge Alignments Stonehenge is widely documented for its solar alignments, particularly the summer solstice sunrise behind the Heel Stone. Less prominent, but noted in archaeological literature, is the relationship between the four Station Stones and the extreme positions of the Moon during a major lunar standstill. These observations suggest that the builders had some awareness of the lunar cycle’s extremes. The evidence remains limited to structural correspondences rather than conclusions about intent. Comparative Sites Several other megalithic structures in Britain and elsewhere have been described as showing possible alignments with lunar extremes. Examples include Calanais in Scotland and the site known as Chimney Rock in the American Southwest. These correlations are part of ongoing archaeoastronomical research and remain subject to interpretation and verification. Notes The major lunar standstill provides an opportunity to observe how extreme lunar positions relate to architectural features at Stonehenge. The present entry records this astronomical context without drawing inferences about cultural meaning or ritual use. Further study would require detailed measurement, longitudinal analysis, and comparison with other structures exhibiting similar alignments. |
