My Roman Curia calendar indicates that the Autumnal Equinox occurs at 2:29 GMT (I like using the retro GMT). So, it occurs today, 23 September in some places. Here at the Steam Pipe Trunk Distribution Venue, the Equinox takes place at 9:29 today, Monday 22 September.
We are at your planet’s tipping point. Day and night are of equal length. From this point onward, for us in the North, days will be increasingly short and nights longer.
At equinox, the dividing line between the sunlit half of Earth and the nighttime half of Earth temporarily passes through Earth’s north and south spin poles. This dividing line is shown in clear detail in the featured video, taken by the Russian meteorological satellite Elektro-L during last year’s September equinox. The Elektro-L satellite is in geostationary orbit over one spot on Earth’s equator and always points directly toward the Earth. The featured video shows a time lapse for an entire day surrounding the equinox, with a new image taken every 30 minutes. Cloud motions are visible as well as the reflection of the Sun are visible as the equinox day progressed. The next Earth equinox is scheduled [by God] for March.
