Chicago, Illinois:  Sunrise, 6:12 a.m. CST; Sunset, 5:51 p.m. CST.  Check local sources for sunrise and sunset times for your location.

Mars continues its eastward march through Taurus.  Find the Red Planet high in the west-southwest after sunset.  It is to the upper left of the Pleiades star cluster, a small bunch of six or seven stars. Together the stars catch your view from the corner of your eye.

Mars is the reddish star immediately to the upper left of the cluster.  Another red star, Aldebaran (“the follower”) – the brightest star in Taurus – is a little farther to the left of Mars.

This evening Mars is above an imaginary line that starts at Aldebaran and goes to the Pleiades star cluster. 

2021, March 9: In this simulated binocular view, Mars is 0.3° to the lower right of 37 Tauri (37 Tau). The Pleiades star cluster is to the lower right in the binocular field.
2021, March 9: In this simulated binocular view, Mars is 0.3° to the lower right of 37 Tauri (37 Tau). The Pleiades star cluster is to the lower right in the binocular field.

With a binocular the star cluster and Mars are still in the same field.  The planet is 0.3° to the lower right of 37 Tauri (37 Tau) on the chart.

The window to see Mars is open for a few hours during the evening.  The view settles lower in the western sky as the night continues, setting over 6 hours after sunset.

Detailed Note: Forty-five minutes before sunrise, the crescent moon (25.7d, 16%) is about 7° up in the southeast.  Saturn – nearly 8° up in the east-southeast – is 7.9° to the upper left of the lunar slice.  At this hour, Jupiter – nearly 4° up in the east-southeast – is 9.1° to the lower left of Saturn.  Fifteen minutes later, Jupiter is over 6° in altitude.  Mercury is 3.5° to the lower left of the Giant Planet.  Use a binocular to see them.  One hour after sunset, Mars is high in the west-southwest, 4.0° to the upper left of Alcyone and 9.6° to the lower right of Aldebaran.  Use a binocular to spot the planet with the starfield with the Hyades and the Pleiades.  Mars is 0.3° to the lower right of 37 Tau, and above a line from Alcyone to Aldebaran.
