29 Jun    Jupiter is a little more than 1 fist-width to the right of the moon, which is a little higher above the western horizon tonight. The moon is less than 10 percent illuminated.

30 Jun    Low in the west at dusk, the thin waxing crescent moon sets only two hours after the sun. Magnitude 1.3 Regulus in the constellation Leo, the Lion, is 1 fist-width to the upper left. The moon is at apogee, 63.65 Earth-radii (406,000 kilometers) away.

1 Jul    Low in the west at dusk, magnitude 1.3 Regulus is 2 finger-widths to the thin waxing crescent moon’s upper right. About 10 percent of the moon’s surface is illuminated.

3 Jul    The moon lies midway between Regulus, 2½ fist-widths to the lower right, and magnitude 0.1 Mars, to the upper right. The moon’s surface is about 20 percent illuminated.

4 Jul    Much closer to Mars tonight, the moon is 1 fist-width to the right of the red planet. Around midnight, earth is at aphelion, its farthest point from the sun for the year. At 1.01682 AU, it’s about 1.5 million miles farther than its average distance of 93 million miles.

5 Jul    Tonight the first-quarter moon passes within a quarter-degree of Mars. Viewing is best as Mars becomes visible in the darkening sky. As evening passes, the moon slides to Mars’ left and is between Mars and Spica when the trio sets early tomorrow morning.
