4 Mar    In the early evening, look for Procyon a little more than 1 fist-width to the moon’s lower right. About 80 percent of the moon’s surface is illuminated. Venus and Jupiter are little more than 4 finger-widths apart tonight.

5 Mar    Mercury reaches its greatest eastward elongation from the sun, 18.2 degrees, which means it sets more than 1½ hours after the sun. Look low in the west at dusk to see Mercury 2½ fist-widths below Venus. Jupiter is less than 4 finger-widths to the upper left.

6 Mar    The moon and Regulus rise about 1½ hours before sunset. The nearly full moon is visible as it rises, even before sunset. Magnitude 1.3 Regulus becomes visible 3 finger-widths to the left of the moon as the sky darkens. Magnitude -1.2 Mars rises an hour after the moon, 1½ fist-widths to the lower left.

7 Mar    Late tonight, the nearly full moon is high in the southeast. Mars is almost 1 fist-width to the moon’s upper left and Regulus is 1½ fist-widths to the upper right. Arcturus is far to the lower left. The distance between Jupiter and Venus is less than 3 finger-widths.

9 Mar    The moon rises 2 hours after sunset, followed an hour later by Saturn. Before midnight, look low in the east to see magnitude 0.4 Saturn 1½ fist-widths to the moon’s lower right. The bright star between them is magnitude 1.2 Spica. Only 2 finger-widths separate Jupiter and Venus.

10 Mar    The moon is at perigee, 56.82 Earth-radii, 362,000 kilometers, away.

26 Feb    Jupiter is less than 2 finger-widths to the moon’s left tonight. Less than 20 percent of the moon’s surface is illuminated.

27 Feb    Jupiter, Venus and the moon line up again tonight. The moon is on top, with Jupiter 1 fist-width below and Venus a little more than one fist-width beyond Jupiter. About 25 percent of the moon’s surface is illuminated. The moon is at apogee, 63.47 Earth-radii, 405,000 kilometers, away.

28 Feb    The Pleiades Cluster is less than 2 finger-widths to the moon’s upper right tonight.

29 Feb    Leap day. Aldebaran is 2 finger-widths to the moon’s lower left tonight. Orion is farther left.

1 Mar    High in the west at midnight, Aldebaran is a little more than 1 fist-width to the moon’s lower right with Orion to the lower left. The Gemini Twins are far to the upper left.

2 Mar    At dusk, look for Aldebaran far to the right or upper right of the moon. Orion is to the lower right and the Gemini Twins are to the left or lower left. The bright star 2½ fist-widths to the moon’s lower left is magnitude 0.5 Procyon.

3 Mar    Now’s a good time to begin watching Venus and Jupiter every evening. Tonight they are less than 1 fist-width apart with Jupiter to the upper left of Venus.

24 Feb    Jupiter, Venus and the waxing crescent moon line up in the west this evening. The moon is closest to the horizon with magnitude -4.2 Venus 1 fist-width to the upper left and magnitude -2.2 Jupiter 1½ fist-widths beyond Venus. Only 5 percent of the moon’s surface is illuminated.

25 Feb    Venus is 1 finger-width to the moon’s lower left this evening.
