What’s Up for September
What are some skywatching highlights in September 2026?
The Moon joins a tea party, Venus reaches peak brilliance, the seasons change, and the Harvest Moon meets up with some planetary neighbors.
From September 14 through 20, use the Moon as a guide to spot Antares, the Teapot asterism, and - under especially dark skies - the center of our Milky Way galaxy.
On September 18, look low in the west shortly after sunset as Venus reaches peak brilliance for this evening appearance.
On September 19, celebrate International Observe the Moon Night! People around the world are invited to look up and connect with our nearest celestial neighbor while learning more about lunar science, exploration, and the many ways the moon has shaped cultures worldwide.
The September equinox arrives on September 22, marking the start of fall in the Northern Hemisphere and spring in the Southern Hemisphere.
Then on September 26, the Harvest Moon rises near Saturn, with faint Neptune completing a wide triangle in the sky. Saturn is visible to the unaided eye, while Neptune requires binoculars or a telescope.
