29 Apr    An annular (ring) eclipse of the sun occurs today. Unfortunately, the full eclipse will only be visible in the uninhabited region of Wilkes Land in Antarctica.

1 May    Low in the west at sunset, magnitude 1.1 Aldebaran is 2 finger-widths to the moon’s lower right. Only 2 days past new, the moon is less than 5 percent illuminated.

2 May    The thin waxing crescent moon lies between Aldebaran, 1½ fist-widths to the lower right, and Jupiter, about 2 fist-widths to the upper left. Orion is hard to miss to the lower left. The moon is about 10 percent illuminated.

3 May    Look for Betelgeuse 1½ fist widths below the moon tonight and Jupiter about 4 finger-widths above. The bright star 1 fist-width above Jupiter is magnitude 1.2 Pollux, the brightest star in Gemini.

20 Apr    Easter Sunday is intended to be the Sunday after the full moon on or after the vernal equinox, assuming the equinox is on 21 March. (It can actually occur between 19-21 March.) The date assumed for the full moon also may not coincide with the astronomical date. As a result, the date of Easter is determined by a formula, Golden Numbers and Epacts, and may fall on any Sunday between 22 March and 25 April.

21 Apr    Low in the south before dawn, the moon is midway between Saturn, 6 fist-widths to the right, and Venus, the same distance to the left. The moon is about two-thirds illuminated.

23 Apr    The moon is at perigee, 57.97 Earth-radii (370,000 kilometers) away.

25 Apr    Look quickly before sunrise to see Venus 2 finger-widths below the moon.

26 Apr    Venus and the moon rise within 5 minutes of each other this morning. The moon is about 10 percent illuminated.

13 Apr    High in the southwest by late evening, Mars is 3 finger-widths to the moon’s lower left, and Spica is 4 finger-widths below Mars.

14 Apr    Only 0.618 AU (92.4 million kilometers) away, Mars makes its closest approach to Earth since January 2008. By midnight, Spica and the moon are high in the southwest, less than ½ finger-width apart.

15 Apr    During April’s full moon, North America will see a total lunar eclipse beginning at about 0200 EDT. Totality begins an hour later and lasts 1 hour and 20 minutes. The moon completely leaves Earth’s umbra at 0533 EDT.

16 Apr    Low in the east at midnight, Saturn is ½ finger-width to the moon’s left. The nearly full moon will likely outshine Saturn, so get out your binoculars. At the southern tip of South America, the moon occults Saturn tomorrow morning.

17 Apr    Saturn stands 1 finger-width to the moon’s right before dawn.

18 Apr    Low in the south before dawn, magnitude 1.1 Antares is 3 finger-widths to the moon’s lower left and Saturn is 1½ fist-widths to the lower right.
