Mars continues as the lone bright planet in the evening sky that is less than two-thirds of the way up in the sky above the west-southwest horizon.  It is marching eastward in the constellation Taurus.

Mars is nearly 9° to the right of Aldebaran (“the follower”), the brightest star in the constellation.  Aldebaran and Mars have nearly the same color and brightness.  The planet is now to the upper left of the Pleiades after their conjunction about a week ago.

2021, March 11: In this simulated binocular view, Mars is 0.8° to the upper left of 37 Tauri (37 Tau). The Pleiades star cluster is still in the binocular field of view with the planet.

Use a binocular to see the background stars with Mars.  Tonight, the Red Planet is 0.8° to the upper left of 37 Tauri (37 on the chart.)

Detailed Note: Saturn and Jupiter are easier to see in the predawn sky.  They are appearing higher in the sky each morning.  Forty-five minutes before sunrise, Saturn is over 8° in altitude above the southeast horizon.  Jupiter is over 9° to Saturn’s lower left and about 4° up in the sky in the east-southeast.  Fifteen minutes later, Mercury is 4.0° up, 5.4° to the lower left of Jupiter.  We say good-bye to Mercury for this apparition.  With exceptional conditions you should be able to track it for a few more mornings before it is lost in the sun’s brilliant light.  One hour after sunset, Mars (m = 1.1) is less than 60° in altitude above the west-southwestern horizon, among the stars of Taurus. It is to the upper left of the Pleiades and nearly 9° to the right of Aldebaran. Use a binocular to spot it 0.8° to the upper left of 37 Tau.
