"How beautifully leaves grow old.
How full of light and color are their last days."
~John Burroughs
During the equinox, the Sun crosses what we call the “celestial equator”—an imaginary extension of Earth’s equator line into space. The equinox occurs precisely when the Sun’s center passes through this line. When the Sun crosses the equator from north to south, this marks the autumnal equinox; when it crosses from south to north, this marks the vernal or spring equinox. Tomorrow 09/22/2020 is this year's autumnal equinox.
