7 Nov
Look low in the west at dusk to see the moon between magnitude 1.4 Mars, 1 finger-width to the upper right, and magnitude 1.1 Antares, less than 1 finger-width to the lower left. But look quickly, because they set only an hour after the sun. Compare the color of Mars and its rival, Antares, the heart of the Scorpion. Daylight saving time ends this morning. Use binoculars.

9 Nov
The waxing crescent moon is just above the dome of the Teapot constellation, Sagittarius.

10 Nov
In the eastern sky, magnitude -4.4 Venus is high enough to be easily visible before sunrise. Magnitude 1.2 Spica is 2 finger-widths to its upper right. Use binoculars.

13 Nov
Look high in the south at dusk to spot magnitude 3.1 Sadalsuud, 2 to 3 finger-widths to the moon’s upper right. Use binoculars to find magnitude 4.8 xi Aquarii midway between them. Then look 3 finger-widths below the moon to see magnitude 3.0 Deneb Algedi. First-quarter moon at 1639 UT. Use binoculars.
