20 May    The western United States is in for a treat as the moon passes directly between Earth and the sun, causing an annular eclipse. The moon covers slightly less than 95 percent of the sun, which appears as a ring, or annulus, around the moon. The maximum eclipse begins at 1830 across much of northern California, an hour later in New Mexico and an hour after that in western Texas.

22 May    Low in the west at dusk, magnitude -4.3 Venus is 3 finger-widths to the moon’s right. Using binoculars, see if you can spot magnitude 1.8 Elnath 1 finger-width beyond Venus.

23 May    The moon sets 1½ hours after sunset and is only about 5 percent illuminated. The moon is at the base of Gemini with Venus far to the lower right.

25 May    Tonight, the Gemini Twins, Pollux and Castor, are more than 1 fist-width to the moon’s right.

6 May    The full moon rises late tonight in the head of the Scorpion, Scorpius. Before dawn tomorrow, they are low in the southwest. The moon is at perigee, 55.97 Earth-radii (357,000 kilometers) away. This is the closest approach for the year. Expect very high tides as perigee occurs only 0.1 hour before the full moon.

8 May    Low in the south at first light, Antares is to the moon’s lower right and Sagittarius is far to the lower left.

9 May    The moon is above the dome of the Teapot constellation, Sagittarius, this morning.

11 May    Just before dawn, look for magnitude 0.9 Altair 2½ fist-widths above the waning gibbous moon. About two-thirds of the moon’s surface is illuminated.
