1 Oct The moon sets early, making tonight great for stargazing. Look for Saturn low in the west at dusk, Mars 2 fist-widths to the upper left near Sagittarius and the Summer Triangle directly overhead.
3 Oct At dusk, Venus is 2 finger-widths below the crescent moon. The pair sets within 2 hours of sunset.
4 Oct The moon is at apogee, 63.7 Earth-radii (406,000 kilometers) away.
5 Oct At dusk, Saturn is 2 finger-widths to the moon’s left, and Antares is 3 finger-widths below Saturn.
6 Oct The moon lies between Saturn, 4 finger-widths to the lower right, and Mars, 2 fist-widths to the lower left. Mars passes within 0.2 degrees of Kaus Borealis, at the top of the Teapot constellation Sagittarius.
7 Oct At sunset, Mars is 4 finger-widths to the moon’s lower left. Mars is ½ degree to the left of Kaus Borealis.
8 Oct Mars is 4 finger-widths to the moon’s lower right.
9 Oct In the early evening, bright Altair is 2½ fist-widths above the moon. Look for the other stars in the Summer Triangle: Vega, 3 fist-widths to the upper right, and Deneb, 3½ fist-widths to the upper left.
11 Oct If you have a clear view of the eastern horizon, look for Mercury and Jupiter an hour before dawn. Mercury is 0.79 degrees to Jupiter’s left.
16 Oct The moon is at perigee, 56.11 Earth-radii (358,000 kilometers) away. Perigee occurs 19.4 hours after the full moon, so we can expect tidal extremes.
18 Oct By midnight, the moon passes within 0.34 degrees of Aldebaran.
19 Oct Before dawn, Aldebaran is 1 finger-width to the moon’s lower right.
20 Oct The moon and Betelgeuse rise an hour before midnight.
21 Oct Before dawn, the moon is between Pollux, 1½ fist-widths to the upper left, and Betelgeuse, 2 fist-widths to the lower right. Procyon is the same distance to the lower left.
24 Oct Before first light, Regulus is 4 finger-widths to the moon’s lower left.
27 Oct Low in the southwest at dusk, Saturn, Venus and Antares line up less than 2 finger-widths from each other.
28 Oct Before dawn, Jupiter is less than 1 finger-width to the moon’s upper right.
31 Oct The moon is at apogee, 63.8 Earth-radii (407,000 kilometers) away.
