31 January 2017, 6:20pm to 8:00pm CST
Moon-Venus-Mars


The three will be setting together in the east, in the constellation Pisces. The 4.1 day-old Moon will have Mars to its upper right and Venus to its lower right. At 6:20pm the Moon will be thirty-seven degrees up, and eighteen degrees up at 8:00pm.
Here are the separations...
Moon and Mars, fewer than three-and-one-quarter degrees the whole time
Moon and Venus, fewer than five-and-three-quarters degrees the whole time
Venus and Mars, fewer than five-and-a-half degrees the whole time
The Moon will be a waxing crescent, Venus a little less than half lit. Mars probably will not be seen at the beginning of the time span, but will show itself as twilight fades.

As a bonus, after 7:03pm CST anyone with a binocular can spot Uranus about fifty degrees up the southwest (also in Pisces), exactly one degree east of the magnitude 5.2 F-class star Zeta Piscium.

The beautiful triangle has been stretched out of shape, but the lineup of Venus, Mars and the Moon tonight is noticeable if only because the "line" now extends upward to Uranus. Uranus lies seven degrees away from the Moon in Pisces. One may be able to pick out Uranus right now with a binoc, but I'd give it another half-hour when there will be complete darkness.

Moon-Saturn


The two will be rising together in the east, in the constellation Ophiuchus (Saturn less than a quarter-degree from the Sagittarius border). The 23.6 day-old Moon will have Saturn to its lower left, the pair remaining fewer than seven degrees apart the whole time. At 4:49am the Moon will be twenty-nine degrees up, and thirty-three degrees up at 5:19am.

Moon-Jupiter-Spica


The three will be rising together in the east, in Spica's home constellation of Virgo. The 17.2 day-old Moon will have Jupiter to its upper right (the pair remaining fewer than five degrees apart the whole time) and Spica to its lower right (the pair remaining fewer than seven degrees apart the whole time). Jupiter and Spica will stay between four-and-a-half and five degrees apart. At 10:40pm the Moon will be sixteen degrees up, and twenty-five degrees up at 11:30pm.

Moon-Jupiter


The two will be rising together in the east, in the constellation Virgo. The 12.2 day-old Moon will have Jupiter to its upper right, the pair remaining fewer than four degrees apart the whole time. At 9:17pm the Moon will be forty-seven degrees up, and fifty-four degrees up at 10:17pm.

NOTE: At this time the magnitude 5.8, A-class star 44 Virginis will be slightly above the straight line connecting the Moon and Jupiter. Can it be seen in the glow of the waxing gibbous Moon?

The conjunction tonight was nice. Regarding 44 Virginis, I used an AstroScan at ~17.9x to see not only it but 46 Virginis (mag 6.0, K-class) as well. Of course, I had to place the Moon out of the field-of-view, and the stars' colors really weren't apparent.
