Today, at 10:29 p.m. Eastern “daylight” time, Earth’s equatorial plane intersects the center of the Sun’s disk.
Sunrise and sunset occur due east and due west, respectively, from all points on Earth’s surface.
Equinox, man!
Days and nights will continue to get shorter in the northern hemisphere, as they’ve been doing since the June solstice, culminating in the shortest day of the year (and longest night) at the December solstice.
Enjoy the equilibrium today!
