7 Apr The moon is at perigee, 56 Earth-radii (357,000 kilometers) away, its second-closest approach for the year. Because perigee occurs only 6 hours after the new moon, expect extreme tides.
8 Apr Low in the west at dusk, Mercury is a little more than 3 finger-widths to the moon’s lower right.
10 Apr Aldebaran is ½ finger-width to the moon’s lower right, low in the west at sunset.
11 Apr The moon lies between Capella, 3 fist-widths to the upper right, and Betelgeuse, 1 fist-width to the lower left.
12 Apr The star just ½ finger-width to the moon’s lower left is Alhena in the constellation Gemini.
13 Apr The moon lies between Procyon, 1 fist-width to the lower left, and Pollux, the same distance to the upper right.
15 Apr The equation of time is zero.
16 Apr Regulus is 1 finger-width above the moon high in the south at sunset.
17 Apr Jupiter is 1 finger-width to the moon’s upper left this evening.
18 Apr At its greatest elongation, 19.9 degrees east of the sun, Mercury sets 1¾ hours after the sun.

26 Apr Low in the southwest before dawn, Saturn is 4 finger-widths to the moon’s lower right, and Mars is the same distance beyond Saturn. Antares is 2 finger-widths to Mars’ lower left. Compare the red/orange colors of Mars and Antares, the rival of Mars.
