Mars continues its eastward march through Taurus.  While not as bright as it was several weeks ago, it is easily found between the Pleiades star cluster and the Hyades star cluster.  The planet is about the same brightness and color as Aldebaran, the brightest star in Taurus.

Aldebaran and the Hyades star cluster, a “check-mark shape,” is the face and head of the Bull.  Together, the star and star cluster make the “V of Taurus.”  Gamma Tauri (γ Tau on the chart) is at the point of the celestial letter. This evening Mars passes 7.2° to the upper right of the star.

Mars in a few evenings Mars is near Kappa Tauri (κ Tau) and Upsilon Tauri (υ Tau).  Make nightly observations of the planet’s position compared to the starry background.

Notice that Mars is approaching a line that starts at Aldebaran and goes through Epsilon Tauri (ε Tau).
