31 Aug    The moon joins Saturn and Mars tonight. Saturn is 1 finger-width to the moon’s right, and Mars is 1½ finger-widths to the lower left. The moon is about 25 percent illuminated.

1 Sep    The moon is in the head of the Scorpion this evening. Antares, the Scorpion’s heart, is 1 fist-width to the lower left. Mars and Saturn are 1 fist-width to the lower right.

2 Sep    The first-quarter moon is low in the south at sunset. Antares is 1 fist-width to the lower right, and Sagittarius, the Teapot constellation, is to the lower left.

3 Sep    The waxing gibbous moon is 1 fist-width above the Teapot’s dome tonight.

5 Sep    Magnitude –3.9 Venus passes within 0.73 degrees of magnitude 1.3 Regulus low in the east before first light. They should be visible with binoculars after Venus rises, an hour before the sun.

6 Sep    As soon as the sky darkens tonight, look 3 fist-widths above or to the upper right of the moon for magnitude 0.9 Altair, in the constellation Aquila, the Eagle that carried thunderbolts for Zeus. About 85 percent of the moon’s surface is illuminated.

15 Sep    In the early evening, look 2½ fist-widths above the moon to find magnitude 0.9 Altair in the constellation Aquila, the Eagle. The moon is at perigee, 56.7 Earth-radii (228,000 miles) away.

16 Sep    Using binoculars, look for Saturn 2 finger-widths above Venus low in the west at dusk. Venus pulls to Saturn’s left over the next few nights.

17 Sep    The nearly full moon is more than 90 percent illuminated and rises a little more than an hour before sunset.

19 Sep    The full moon (1113 UT) closest to the autumnal equinox is called the Harvest Moon.

20 Sep    Rising a half hour after sunset, the moon is high in the southeast by midnight and still appears full.

21 Oct    At evening twilight, magnitude 0.9 Altair, in the Summer Triangle, is 2½ fist-widths above the waxing gibbous moon low in the south. The triangle’s other stars are magnitude 0.1 Vega, 3 fist-widths to Altair’s upper right, and magnitude 1.3 Deneb, 2 fist-widths to Vega’s upper left or nearly overhead.

22 Oct    In the south at sunset, magnitude 0.9 Altair—in the constellation Aquila, the Eagle—is 2½ fist-widths to the first-quarter moon’s upper right. In Greek mythology, the eagle Aquila carried Zeus’ thunderbolts.

23 Oct    High in the south at sunset, the waxing crescent moon lies between two third-magnitude stars, so get out your binoculars. Magnitude 3.1 Sadalsuud in Aquarius, the Water Bearer, is 2 finger-widths above the moon, and magnitude 3.0 Deneb Algedi—in the constellation Capricornus, the Sea Goat—is little more than 3 finger-widths below the moon.

25 Oct    Saturn, in conjunction with the sun, passes behind it.

26 Oct    Mercury reaches its greatest elongation east, 24.1 degrees from the sun. Look quickly at dusk to spy Mercury before it slips below the western horizon.

27 Oct    Rising less than an hour before sunset, the nearly full moon is high in the east as the stars appear. Directly above the moon, the Great Square of Pegasus includes three stars from the constellation Pegasus and one borrowed from neighboring Andromeda. The nearest star of the square is magnitude 2.9 Algenib, 1 fist-width above the moon. Magnitude 2.6 Markab is 1½ fist-widths to the upper right, and magnitude 2.6 Scheat is 1½ fist-widths to the upper left. Andromeda’s magnitude 2.1 Alpheratz, 1½ fist-widths to the lower left, completes the square.
