6 Feb     At dusk, look for the thin waxing crescent moon 2 to 3 fist-widths above the western horizon. Three finger-widths to the left, you will find magnitude -2.1 Jupiter. Only about 10 percent of the moon’s surface is illuminated. The moon is at apogee, 252,277 miles or 63.64 Earth-radii away.

7 Feb     Jupiter is 1 fist-width below the moon tonight.

8 Feb     Tonight, the moon moves another fist-width above Jupiter. The star a little more than 1 fist-width above the moon is magnitude 2.2 Hamal.

9 Feb     Hamal is 3 finger-widths to the moon’s right or upper right tonight.

11 Feb    The moon lies between the Pleiades, 1 finger-width to the right or lower right, and Aldebaran, 1 fist-width to the left or upper left depending on when you look tonight. The equation of time is at the minimum for the year, -14.25 minutes. This means that when the clock is at noon (mean time), the sun lags behind and won’t reach the meridian for another 14 minutes. Use binoculars. First-quarter moon at 0718 UT

12 Feb    Aldebaran is 4 finger-widths below the moon this evening. Orion is to the lower left.
