18 May    Less than 24 hours past new. the moon sets not quite an hour after the sun and will be hard to spot low in the west at dusk. Look for Aldebaran ½ finger-width to the moon’s upper left. Mercury is nearly 4 finger-widths to the upper right.

20 May    The moon lies midway between Venus, 1 fist-width above, and Betelgeuse, below or to the lower left.

21 May    Low in the west at dusk, Venus is 4 finger-widths to the moon’s right. Procyon is 1 fist-width to the left or lower left.

22 May    The moon lies in the middle of a triangle formed by Venus, 1½ fist-widths to the lower right, Procyon, 1 fist-width below, and Jupiter, 1½ fist-widths to the upper left. Saturn reaches opposition at 2200 EDT. Lining up opposite the sun, it rises around sunset and sets around sunrise.

23 May    Jupiter is 2 finger-widths to the moon’s upper right tonight.

4 May    The moon lies 4 finger-widths to Jupiter’s left, high in the west at sunset. Procyon is 1 fist-width to the moon’s lower left.

5 May    Procyon is a little more than 1 fist-width below the moon at dusk.

6 May    The moon is at apogee, 63.39 Earth-radii (404,000 kilometers) away.

7 May    Regulus is 3 finger-widths to the first-quarter moon’s upper left, high in the south at dusk.

8 May    Regulus is 1 fist-width to the moon’s upper right this evening. Mars is 3 fist-widths to the lower left. Noticeably dimmer Spica is 1½ fist-widths beyond Mars.

9 May    Mars is 1½ fist-widths to the moon’s lower left tonight.

10 May    High in the southeast at dusk, Mars stands about 2 finger-widths to the moon’s left. Saturn, at opposition, rises at sunset and is visible all night.

6 Apr    High in the southwest at dusk, Jupiter is less than 3 finger-widths to the moon’s upper right. Procyon is 1½ fist-widths to the lower left.

7 Apr    The first-quarter moon lies midway between Pollux, 1 fist-width to the upper right, and Procyon, the same distance to the lower left. Jupiter is nearly 1½ fist-widths to the right.

8 Apr    Mars is at opposition, meaning it is opposite the sun when viewed from Earth. Mars rises at sunset and remains in the sky all night.

10 Apr    High in the south early tonight, bright Regulus is 2 finger-widths above the moon.

12 Apr    The moon lies between Regulus, 3 fist-widths to the upper right, and Mars, 2 fist-widths to the lower left.

5 Jan    Jupiter makes its closest approach to Earth at opposition. Jupiter’s face is fully illuminated by the sun, making this the best time to view the planet and its moons. With a good pair of binoculars, you should be able to see Jupiter’s four largest moons, which appear as bright dots on either side of the planet. At magnitude –2.7, Jupiter outshines everything else in the area.  As evening passes, Jupiter climbs the eastern sky and is high in the southeast at midnight.

6 Jan    High in the south at dusk, the moon sets seven hours after the sun. About 25 percent of the moon’s surface is illuminated.

8 Jan    Rising at midday, the first-quarter moon is high in the south at dusk and sets after midnight.

10 Jan    Two-thirds of the moon’s surface is illuminated. High in the southeast at dusk, the moon is above the constellation Taurus the Bull. Orion, the Mighty Hunter, lies on its side below Taurus.

11 Jan    High in the southeast in the early evening, the Seven Sisters (Pleiades Cluster) are less than 1 fist-width above or to the upper right of the moon, and magnitude 1.1 Aldebaran is 2 finger-widths below or to the lower left. Orion lies beyond Aldebaran. Venus is at inferior conjunction, passing between Earth and the sun. Venus will soon be visible in the pre-dawn sky.

2 Dec    By midnight, the moon sits high in the east with magnitude 0.5 Procyon 1 fist-width to the right, the Gemini Twins 1½ fist-widths to the upper left, and the Big Dipper standing on its handle far to the lower left.

3 Dec    Jupiter is at opposition (on the opposite side of the earth from the sun).

4 Dec    Late tonight, Regulus is nearly 3 finger-widths to the waning gibbous moon’s left. About 75 percent of the moon’s surface is illuminated. Mercury reaches its greatest elongation 20.5 degrees west of the sun, which means it sets nearly an hour after the sun.

5 Dec    High in the south before dawn, Regulus is 2 finger-widths above the moon. Using binoculars, see if you can spot the two stars between them, magnitude 4.9 pi Leonis and magnitude 4.6 31 Leonis

6 Dec    With the moon rising well after midnight, tonight’s dark skies make for good stargazing. At dusk, look for Cygnus, the Swan, high in the west at dusk. First find the Summer Triangle’s three bright stars: Altair at the lower left corner, Vega at the lower right corner, and Deneb at the top. Magnitude 2.3 Sadr is 3 finger-widths to Deneb’s lower left. The two stars 4 finger-widths at right angles from Sadr make up the wings. Continuing in a straight line from Deneb through Sadr another 1½ fist-widths completes the neck and head of the Swan.

8 Dec    During the next few days, look to the southeast before dawn as the moon passes by one star and three planets: Spica, Saturn, Venus and Mercury. This morning, the moon, the star and the planets line up from the upper right to the lower left. From the moon, measure 1 fist-width to the lower left to magnitude 1.2 Spica. Moving another fist-width to the lower left takes us to magnitude 0.6 Saturn. One more fist-width brings us to magnitude -4.0 Venus. Finally, 3 finger-widths beyond Venus is magnitude -0.5 Mercury.

15 Apr    The equation of time is zero, which means apparent (sundial) and mean solar (clock) time are the same. At opposition, Saturn rises around sunset. Spica is 2 finger-widths to the right.

16 Apr    The thin waning crescent moon rises 2½ hours before the sun. Less than 25 percent of the moon’s surface is illuminated.

18 Apr    At its greatest elongation west of the sun, 27.5 degrees, Mercury rises nearly a half hour before the sun.

19 Apr    The moon and Mercury rise side by side an hour before sunrise. Only about 5 percent of the moon’s surface is illuminated.

21 Apr    The Lyrids meteor shower peaks tonight and tomorrow morning, and the new moon makes for favorable viewing.

23 Oct    The waning crescent moon rises less than 4 hours before the sun. Look for Regulus and Mars above the moon and the Big Dipper standing on its handle far to the left. About 20 percent of the moon’s surface is illuminated.

26 Oct    The moon is at perigee, 55.98 Earth-radii, or 357 kilometers, away. The year’s second closest, perigee occurs a little more than 7 hours before the new moon, so we can expect tidal extremes. New moon at 1956 UT

28 Oct    Rising at sunset, Jupiter reaches its brightest magnitude of the year at -2.9. At 2200 EDT or 0200 UT, Jupiter is at opposition as Earth passes between it and the sun.
