Throughout September, Neptune will be located among the stars of northeastern Aquarius, about a fist’s diameter to the upper right (or 10.5 degrees to the celestial west-southwest) of Jupiter. Around opposition, Neptune’s apparent disk size will peak at 2.4 arc-seconds and its large moon Triton will be the most visible (inset). local time, when the blue planet has risen higher. Good binoculars (green circle) will show it, too, if your sky is very dark. Since it’s directly opposite the sun in the sky, Neptune will be visible all night long in backyard telescopes. Blue Neptune will shine with a slightly brighter magnitude 7.8. At that time the distant planet will be closest to Earth for this year – a distance of 2.68 billion miles, 4.32 billion km, 4 light-hours, or 28.91 Astronomical Units. On Friday, September 16, Neptune will reach opposition. Saturday, September 10 - Bright Moon near Neptune and Jupiter (all night) This phenomenon traditionally allowed farmers to work into the evening under bright moonlight - hence the name. But the shallow slope of the evening ecliptic (and the moon’s orbit) around the equinox causes Harvest Moons to rise at almost the same time each night – only delayed by as little as 10 minutes, depending on your latitude.

On the evenings around its full phase, the moon normally rises about 50 minutes later than the previous night. Because this is the closest full moon to the autumnal equinox in 2022, it is also the Harvest Moon. Full moons always rise around sunset and set around sunrise. The indigenous Anishinaabe people of the Great Lakes region call this moon Waatebagaa-giizis or Waabaagbagaa-giizis, the Leaves Turning or Leaves Falling Moon.
The September full moon, traditionally known as the “Corn Moon” and “Barley Moon”, always shines in or near the stars of Aquarius and Pisces. Monday, September 5 - Venus Veers past Regulus (before sunrise) On the opposite side of the mare is the distinctive, round Sinus Iridum, the Bay of Rainbows. The Montes Carpatus ring the south, near crater Copernicus. They sink out of sight near the prominent crater Eratosthenes. The southeastern edge of Mare Imbrium is bordered by the lengthy Apennine Mountains, or Montes Apenninus. That mountain range disappears under a lava-flooded zone connecting Mare Imbrium with Mare Serenitatis to the southeast. To the lower right (lunar southeast) of the Alps are the Caucasus Mountains, or Montes Caucasus. Binoculars or a telescope will reveal a slash cutting through them called the Alpine Valley, or Vallis Alpes, where the moon’s crust has dropped between parallel faults. The most northerly arc of mountains is the Lunar Alps, or Montes Alpes. Sunday, September 4 will offer a fine opportunity to view the spectacular, mountain chains, actually segments of the old basin’s rim, that encircle the rim of Mare Imbrium.
