Today:
As the dusk fades at 8:30 PM, the Crescent Moon shines barely to the right of Castor, the rightmost of the Gemini Twins. Below and a little farther to the right, in the west-northwest, shines Jupiter, bounded by the horns of Taurus. Jupiter and the horns of Taurus will sink below the horizon by midnight, the moon and the Twins following suit between 1:00 and 1:45 AM.
Saturday:
When looking toward the west this evening as the twilight dims, you’ll see that the moon is no longer next to Castor of the Gemini Twins, but has shifted up and to the left, appearing within the constellation Cancer, and immediately to the right of Mars. Mars will closely approximate its position relative to Cancer tomorrow night, but the fickle and flighty moon, will have moved halfway toward Leo, the Lion.
Sunday:
High in the southwest in the failing twilight, the First Quarter Moon appears halfway between Mars and Regulus, the brightest star in Leo. Regulus sits very close to the path of the Sun, the same general path that the Moon follows, so these two have a regularly scheduled meeting every 27 days and 8 hours, the next meeting coming tomorrow evening.
