14 Apr    The waxing crescent moon is less than 2 finger-widths to Jupiter’s left or upper left at dusk.

15 Apr    Three prominent constellations surround the moon tonight: Orion to the lower left, Gemini to the upper left and Taurus to the lower right. Home to the navigational star Capella, the lesser-known constellation Auriga, the Charioteer, is to the moon’s upper right. The moon is at apogee, 63.48 Earth-radii, or 405,000 kilometers, away. The equation of time is zero, which means sundial (apparent solar) time and mean solar time are the same.

16 Apr    Gemini’s brightest stars, Pollux and Castor, are 1½ fist-widths above the moon tonight. Magnitude 1.9 Alhena is 1 finger-width below the moon. Less than a third of the moon’s surface is illuminated

17 Apr    The waxing crescent moon lies midway between magnitude 1.2 Pollux, 1 fist-width to the upper right, and magnitude 0.5 Procyon, to the lower left.

18 Apr    Procyon is a little more than 1 fist-width to the first-quarter moon’s lower right, and magnitude 1.3 Regulus is 2½ fist-widths to the moon’s upper left.

20 Apr    Regulus is less than 3 finger-widths above or to the upper left of the waxing gibbous moon, high in the south at dusk. About two-thirds of the moon’s surface is illuminated.
