23 Jun    The moon rises 2½ hours before the sun this morning and is followed 40 minutes later by magnitude -3.9 Venus about 1 fist-width to the lower left. The Pleiades Cluster is 3 finger-widths to Venus’ upper left.

24 Jun    The moon and Venus rise together this morning, less than 2 hours before the sun. The moon is only 1 finger-width to Venus’ lower right. The moon is only 10 percent illuminated.

25 Jun    The moon rises just before the sun for the next few days, giving us dark evenings for stargazing. Let’s look at some of the night sky’s less obvious features. Start in the west with the constellation Leo, the Lion, whose brightest star, magnitude 1.3 Regulus, is easy to spot. How many of the other stars can you see with your  binoculars? Most are third magnitude and dimmer except for one second-magnitude star, magnitude 2.2 Denebola, 2½ fist-widths to Regulus’ upper left.

26 Jun    Look high overhead tonight. Find Arcturus by following the arc of the Big Dipper’s handle. Arcturus is the brightest star of the constellation Boötes, the Herdsman. Many believe that Boötes looks more like a kite. None of the stars are brighter than third magnitude.

27 Jun    Turning to the south, Scorpius, the Scorpion, dominates the area near the horizon. Magnitude 1.1 Antares is its only first-magnitude star.

28 Jun    Low in the west after sunset, magnitude -1.8 Jupiter is 2 finger-widths to the very thin moon’s upper right. The moon sets less than an hour after the sun.

14 Jul    Low in the southwest at dusk, the bright star 4 fist-widths above the waxing crescent moon is magnitude 0.2 Arcturus in the constellation Boötes, the Herdsman. The Big Dipper is far to the moon’s upper right. Follow the arc of the dipper’s handle to Arcturus, and continue on until you see magnitude 1.2 Spica.

15 Jul    Tonight the moon passes within ½ finger-width of magnitude 1.2 Spica. Viewers in Hawaii will see the moon occult Spica.

16 Jul    Magnitude 0.6 Saturn is 2 finger-widths to the moon’s upper right tonight. First-quarter moon at 0318 UT

18 Jul    The moon is in the head of Scorpius, the Scorpion, this evening. Magnitude 1.1 Antares, the Heart of the Scorpion, is 3 finger-widths to the lower left.

19 Jul    The waxing gibbous moon rises 3 hours before sunset and is low in the south as the sun sinks below the western horizon. Traveling across the night sky, the moon sets a little more than two hours before sunrise tomorrow. More than 80 percent of the moon’s surface is illuminated.
