One hour after sunset, Mars is over halfway up in the sky above the west-southwest horizon. The Red Planet is marching eastward in Taurus.  It is above the “V” of Taurus that is made by Aldebaran, “the follower,” and the Hyades star cluster.

The planet is moving toward the Bull’s horns, Elnath, “the one butting with horns,” and Zeta Tauri (ζ Tau on the chart). Watch Mars move between the horns on April 12 and April 13.

2021, March 29: Through a binocular Mars is 2.8° to the upper left of Tau Tauri (τ Tau), 3.2° to the right of Iota Tauri (ι Tau).

Use a binocular to spot the starry background with the planet.  Mars is 2.8° to the upper left of Tau Tauri (τ Tau on the chart) and 3.2° to the right of Iota Tauri (ι Tau).

2021, March 29: Two hours after sunset, the bright moon is 7.0° to the lower left of Spica.

Two hours after sunset, the bright moon is less than 10° up in the eastern sky.  The lunar orb is 7.0° to the lower left of Spica, “the ear of corn,” the brightest star in Virgo.

Their grouping is a sign that spring is here.  It is important to note that the moon passes Spica each month.  The full moon is near the star near the beginning of spring.  This year this occurs nine days after the equinox.

Detailed Note: One hour before sunrise, the moon (16.0d, 99%) is nearly 20° above the west-southwestern horizon, 8.2° to the upper right of Spica (“the ear of corn,” α Vir, m = 1.0).  Farther eastward along the ecliptic, Saturn is nearly 12° up in the southeast.  Brighter Jupiter – nearly 7° in altitude above the east-southeastern horizon – is 11.5° to the lower left of the Ringed Wonder. One hour after sunset, Mars is nearly 50° up in the west-southwest.  Among the stars of Taurus, it is 2.8° to the upper left of τ Tau, 3.2° to the right of ι Tau, and 8.5° below Elnath.  Two hours after sunset, the moon (16.7d, 97%), less than 10° up in the east, is 7.0° to the lower left of Spica.
