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.
