This year, the first time since 1991, the full moon that's called the Harvest Moon rose on the same day as the summer ended and autumn began with the autumnal equinox on Wednesday night, nearly at midnight.
I didn't know the origin of the name "harvest moon" until I heard on the radio program "Stardate" that it is the full moon closest to the September equinox. I saw it myself when it was at its fullest, walking the dog in the early morning hours as it reached the western horizon, ready to set.
I learned that it's called the harvest moon, because farmers used its bright celestial light to extend the day for harvesting in the fields.
This year, the bright star right next to it is Jupiter. It's the closest Jupiter has been to the moon since 1963.
If my memory is right, the Harvest Moon won't come this close to the actual day of the equinox again until 2029. Since the moon's cycle is less than 30 days, it comes on different days during the season. Sometimes the Harvest Moon is as late as October.
Did you notice the beautiful, very round, enormous moon in the sky? At midnight it was so bright it actually cast shadows.
