One hour after sunset look for Mars high in the west-southwest. During the night, the planet and background stars appear lower in the sky, setting about 6 hours after sunset.
The planet is to the upper left of the Pleiades star cluster and to the right of the “V” of Taurus with Aldebaran, the constellation’s brightest star.
Mars is to the upper left of 37 Tauri (37 Tau on the chart). It is moving toward Kappa Tauri (κ Tau) and Upsilon Tauri (υ Tau). Use a binocular to watch it approach the stellar pair during the next few evenings.
Mars continues its eastward march, moving toward Elnath and Zeta Tauri, the Bull’s Horns. It moves between them during mid-April.
