Both are part of the Summer Triangle.

24 Aug    Rising two hours after sunset, the waxing gibbous moon is low in the east by midnight. The brightest nearby stars are magnitude 2.1 Alpheratz 3 fist-widths above the moon, magnitude 2.2 Hamal 1½ fist-widths to the left and magnitude 2.3 Almach 3 fist-widths to the upper left. The slightly brighter star 1½ fist-widths to the lower left of Almach is magnitude 1.9 Mirfak in the constellation Perseus, the Hero.

11 Aug    Tonight, the bright star 2 finger-widths to the moon’s upper left is magnitude 1.2 Spica. The Perseid meteor shower peaks over the next few nights. Viewing will be better after the moon sets, 2 to 3 hours after sunset.

12 Aug    Magnitude 0.7 Saturn is 2 finger-widths to the moon’s upper left tonight. Spica is 4 finger-widths to the moon’s lower right. About 25 percent of the moon’s surface is illuminated.

13 Aug    The moon is in the constellation Libra, the Scales, this evening. With binoculars, you should have no trouble spotting magnitude 2.9 Zubenelgenubi, less than 1 finger-width to the moon’s right. The moon is about one-third illuminated.

14 Aug    The first-quarter moon (1056 UT) stands to the right of Scorpius, the head of the Scorpion constellation.

15 Aug    Antares is 4 finger-widths to the moon’s lower right tonight.

16 Aug    The moon stands above the top of Sagittarius, the Teapot constellation.

17 Aug    Rising 3 hours before sunset, the waxing gibbous moon is low in the south in the early evening with magnitude 0.9 Altair 3 fist-widths to the upper left. Only 3 days from full, the moon is about 80 percent illuminated.

4 Aug     This morning, the moon slips past both Jupiter and Mars, now 3 finger-widths to the moon’s upper left. Magnitude –0.6 Mercury is 1 fist-width to Mars’ lower left. The moon is less than 10 percent illuminated.

5 Aug    Spotting a sliver of moon through your binoculars will be harder this morning as the moon rises only an hour before the sun. Less than 5 percent of the moon is illuminated.

6 Aug    New moon at 2151 UT

7 Aug    The moon sets within a few minutes of the sun, giving us dark evening skies for the next few evenings. Beginning at dusk, look for magnitude –4.0 Venus near the western horizon. Next, look for magnitude 0.2 Arcturus high to the upper left, more than 4 fist-widths from Venus. Magnitude 0.7 Saturn is to Arcturus’ lower left, and magnitude 1.2 Spica is to Saturn’s lower right.

8 Aug    The Scorpion hugs the southern horizon tonight. Magnitude 1.1 Antares is the constellation’s brightest star. The head and claws extend to the right, and the tail curls to the lower left. Sagittarius is to the left of the tail.

9 Aug    The sun sets an hour before the moon tonight. As the sky darkens, use your binoculars to look for magnitude –4.0 Venus 3 finger-widths to the moon’s upper right. Only 5 percent of the moon’s surface is illuminated.

10 Aug    Farther to the left of Venus, the moon sets more than an hour and a half after the sun.

28 Jul    High in the south at first light, the waning gibbous moon is between Alpheratz, 2½ fist-widths to the upper right, and magnitude 2.0 Mira, 2 fist-widths to the lower left in the constellation Cetus, the Sea Monster.

29 Jul    Rising around midnight, the last-quarter moon (1743 UT) is high in the southwest before dawn tomorrow.

30 Jul    Rising 1½ hours before the sun, magnitude 0.2 Mercury reaches its greatest elongation west of the sun and should be visible before the sky brightens. With your binoculars, try spotting magnitude 1.6 Mars 3 finger-widths above Mercury and magnitude –1.9 Jupiter 1½ finger-widths to Mars’ upper right.

31 Jul    High in the east before dawn, look for the Pleiades Cluster 3 finger-widths to the waning crescent moon’s upper left. The moon is about one-third illuminated.

1 Aug    Magnitude 1.1 Aldebaran is 1 finger-width to the moon’s lower right before dawn.

3 Aug    Over the next few days, the waning crescent moon passes by three planets in the pre-dawn sky. This morning look for magnitude –1.9 Jupiter, 3 finger-widths to the moon’s left or lower left, and magnitude 1.6 Mars, 3 finger-widths to Jupiter’s lower left. About 10 percent illuminated, the moon is at apogee, 63.63 Earth-radii (252,000 miles) away.
