Ancient Chinese Eclipse Record Re-examined, Offering Insights into Earth's Rotation and Solar Corona
Researchers have re-examined a 2,700-year-old Chinese record of a total solar eclipse from 709 BCE, using historical geography and modern astronomy. By correcting the ancient capital of Lu Duchy's coordinates, they precisely reconstructed the eclipse's visibility. This allowed for new data on Earth's rotation speed and the Sun's orientation. The study suggests a later addendum describing the Sun as 'completely yellow above and below' might be one of the earliest written accounts of the solar corona.
