22 Sep    Today marks the first day of fall, the autumnal equinox, as the sun crosses the celestial equator into the Southern Hemisphere.

23 Sep    Using binoculars, look for the Pleiades Cluster 3 finger-widths to the moon’s upper left this evening.

24 Sep    High in the southwest before dawn, the Pleiades Cluster is 3 finger-widths to the moon’s upper right, and Aldebaran is less than 1 fist-width to the left.

25 Sep    In the south before dawn, bright magnitude 1.1 Aldebaran is 2 finger-widths to the moon’s lower right. To the moon’s lower left, Orion the Mighty Hunter dominates the southern sky.

26 Sep    Rising shortly after midnight, the first-quarter moon is high in the south before dawn, midway between Jupiter to the lower left and Aldebaran to the upper right. The brightest star in Orion, magnitude 0.6 Betelgeuse, is 1 fist-width below the moon.

27 Sep    Magnitude 1.9 Alhena, in the constellation Gemini, is 1 finger-width below the moon in the pre-dawn sky. The Twins, Pollux and Castor, are nearly 2 fist-widths to the left. Jupiter is 1 fist-width to the moon’s lower left. The moon is at apogee, 63.39 Earth-radii (251,000 miles) away. Last-quarter moon at 0355 UT

28 Sep    The moon is between magnitude –2.2 Jupiter, 3 finger-widths to the upper left, and magnitude 0.5 Procyon, a little more than 1 fist-width to the lower right.

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.

8 Sep    Venus is now to Spica’s upper left, and the thin waxing crescent moon is less than 1 finger-width to Venus’ left. All three occupy a 1½-finger-width diameter circle.

9 Sep    Magnitude 0.7 Saturn is 3 finger-widths to the moon’s right. Less than 20 percent of the moon’s surface is illuminated.

11 Sep    The moon is 3 finger-widths above Antares, the red-orange heart of Scorpius.

12 Sep    First-quarter moon at 1708 UT

13 Sep    The waxing gibbous moon is above the Teapot constellation Sagittarius.

1 Sep    In the east before dawn, the waning crescent moon stands between the Gemini Twins, 1 fist-width to the upper left, and Procyon, the same distance to the lower right. Brilliant magnitude –2.0 Jupiter is 1 fist-width directly above the moon. Less than 20 percent of the moon’s surface is illuminated. The equation of time is zero.

2 Sep    Mars is 3 finger-widths to the slivered moon’s upper left before dawn.

3 Sep    Only two days from new, the moon, about 5 percent illuminated, rises less than two hours before the sun.

5 Sep    Low in the west at dusk, the first light you see is magnitude –4.0 Venus, followed by magnitude 0.7 Saturn, 1 fist-width to the upper left, and magnitude 1.2 Spica, less than 1 finger-width to Venus’ lower left. New moon at 1136 UT

7 Sep    Only a few days old, the moon sets soon after the sun, making stargazing easier. Ursa Major, the Big Dipper, sits a little left of north with its handle pointing to the upper left. The pointer stars at the end of the bucket point toward Polaris, less than 3 fist-widths to the upper right. Looking to the right (east), you can easily make out Cassiopeia, the Lazy W constellation. Turning farther right, now facing south, you can see the Summer Triangle to Cassiopeia’s upper right. Sagittarius and Scorpius are easy to spot near the horizon. Finishing the turn, now facing west, you can see Arcturus, the bright star in the middle of the sky.
