This month, Mars remains in the southwest at dusk this month as it pulls away from Saturn. Mars continues to fade a little each night as Earth continues to leave it farther behind. Mars is near Antares in Scorpius by the end of the month.
Saturn is now lower in the southwest at dusk. It drops into the Sun’s glare late next month.
Venus is now getting harder to see, as it will pass behind the Sun late next month. You can still look for it very low in the east in dawn twilight.
Jupiter is now higher in the east at dawn; it is the brightest thing there until Venus rises.
The Big Dipper is left of the North Star, with its handle pointing up. From that handle, you can ‘arc to Arcturus’ in the west at dusk.
Antares, brightest star of Scorpius, the Scorpion, is in the southwest, with the ‘teapot’ of Sagittarius due south. The Summer Triangle is high overhead. The stars of summer are here. Look for the Great Square of Pegasus rising in the east, indicating that fall is approaching.

At 9:29 pm on Monday, September 22, the Sun is directly overhead at the equator; everyone in the world has the same amount of daylight. This, then, is the autumn equinox. For us the days, which have been getting shorter since June 20, actually become shorter than the nights after this equinox. In the Southern Hemisphere, day becomes longer than night and spring begins.
On most clear Saturday nights at the George Observatory, you can hear me do live star tours on the observation deck with a green laser pointer. If you’re there, listen for my announcement.
