Step outside about an hour before sunrise and look southward. The bright gibbous moon is there. It is to the upper left of the star Antares (“the rival of Mars”). The lunar orb is nearly 75% illuminated, certainly bright enough to cast your shadow.
Farther east, bright Jupiter is low in the east-southeast. Use a binocular to spot the star Deneb Algiedi (“the kid’s tail”) to the bright planet’s lower right. Saturn is about 12° to the upper right of Jupiter.
Jupiter is moving eastward faster than Saturn as it opens a gap on the Ringed Wonder.
During the evening, Mars is over halfway up in the sky in the west. It is in front of the starry background of Taurus, continuing its eastward march. It is heading toward the horns of the Bull. This evening it is 6.4° to the lower left of Elnath (“the one butting with horns”) that marks the Bull’s Northern Horn. The second horn is Zeta Tauri (ζ Tau on the chart.)

Detailed Note: One hour before sunrise, the moon (20.0d, 72%) is 24.0° up in the south. In Ophiuchus, the lunar orb is 7.8° to the upper left of Antares (“the rival of Mars,” α Sco, m = 1.0). Farther east, bright Jupiter is nearly 8° above the east-southeastern horizon. Jupiter is 1.9° to the upper left of Deneb Algiedi (“the kid’s tail”). Saturn is 12° to Jupiter’s upper right. Deneb (“the hen’s tail,” α Cyg, m = 1.2) sets at sunset. One hour later, Mars – nearly 48° up in the west – is moving eastward in Taurus, near the Bull’s Horns. This evening it is 6.4° to the lower left of Elnath. The second horn is marked by the star Zeta Tauri (ζ Tau on the chart).
