During early evening hours of September 25, the moon appears near Saturn in the southern sky.

During the evening hours of September 25, the moon appears 3.7° to the lower left of Saturn. The gibbous moon is over 70% illuminated.
Jupiter is 7.6° to the lower right of Saturn.
As seen from the sun, Jupiter passes Saturn in a heliocentric conjunction on November 2. This is a prelude to the Great Conjunction on December 21, when Jupiter passes very closely to Saturn. While the planetary pair appears close in the sky, they are hundreds of millions of miles apart in space.
A Great Conjunction occurs every 19.6 years. The last one occurred in 2000. The next Jupiter – Saturn conjunction occurs October 31, 2040, when the two planets rise into the eastern morning sky. The gap is 1.1°. At this year’s conjunction, the two planets appear ten times closer.
While other conjunctions have occurred, this year’s conjunction is the closest Jupiter – Saturn conjunction since 1623. That year’s conjunction occurred after the invention of the telescope and during very bright evening twilight. Read our article about whether it was observed.
The brilliant Morning Star Venus continues to step through Virgo. It is that “bright star in the eastern sky” before sunrise. This morning Venus is near Beta Virginis. In the evening sky, the gibbous moon is between Mars and Jupiter, and near the star Fomalhaut. Mars is in the east-southeast. Jupiter and Saturn are in the east-southeast.
Bright Morning Star Venus continues to sparkle in the eastern sky before sunrise. It shines from in front of the stars of Virgo. Evening planet Mars appears in the eastern sky while Jupiter and Saturn are in the south-southwest. The bright gibbous moon shines from the stars of Capricornus.
In this commentary is a different idea about year-round daylight time, based on astronomical concepts for the mid-northern latitudes. Year-round or not, a different approach may yield better results.
