Autumn Begins Astronomically
Jordanian Astronomical Society President Ammar Al-Sakji said the autumnal equinox will occur at 3:05 a.m. Wednesday Jordan time, marking the astronomical beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
Al-Sakji explained that the equinox occurs when the Sun, in its apparent annual movement, crosses the celestial equator from north to south. He noted that on the day of the equinox, the Sun rises very close to due east and sets very close to due west.
He said the common belief that day and night are exactly equal on the equinox is not entirely accurate from an observational perspective. Daylight lasts slightly more than 12 hours because of atmospheric refraction and because sunrise and sunset are calculated based on the upper edge of the Sun’s disk.
In Amman and its surrounding areas, daylight comes closer to exactly 12 hours several days after the equinox. It will last approximately 12 hours and one minute on September 26 before falling to around 11 hours and 59 minutes on September 27.
Astronomically, autumn will continue this year until the winter solstice on December 21 at 11:50 p.m., lasting approximately 89 days, 20 hours and 45 minutes.
Following the autumnal equinox, the Sun will gradually rise from positions south of due east and set from positions south of due west as viewed from Jordan. Daylight hours will gradually decrease while nighttime hours increase until the winter solstice.
