4 Mar    The last-quarter moon is above Antares before dawn.

5 Mar    The moon is at perigee, 58.01 earth-radii or 370,000 kilometers away.

6 Mar    The waning crescent moon rises 4 hours before the sun and is low in the south at dawn. Sagittarius is to the moon’s lower right. About a third of the moon’s surface is illuminated.

7 Mar    With the moon setting 4 hours before the sun, the dark sky will be perfect for stargazing. Start in the north with the Big Dipper, Ursa Major, the Great Bear. The handle arcs down toward the horizon. Follow the pointer stars at the far end of the dipper 3 fist-widths left to Polaris, the North Star. Another 3 fist-widths beyond Polaris is the Lazy W constellation, Cassiopeia, upside down in the early evening.

8 Mar    Now that you’ve found Polaris, use binoculars to see if you can make out the Little Dipper, Ursa Minor, the Little Bear. Polaris represents the end of the handle or the bear’s tail. This evening the handle extends to the lower right, arcing slightly upward, with the bowl parallel to the horizon. You need a dark sky to see the entire dipper, as only two stars are second magnitude and one is third magnitude. The others are fourth and fifth magnitude.
