Chicago, Illinois:  Sunrise, 6:16 a.m. CDT; Sunset, 7:28 p.m. CDT.  Check local sources for sunrise and sunset times for your location.

Mars is nearly halfway up in the west after sunset.  The planet continues its eastward march through Taurus.  It is far above the “V,” made by Aldebaran and the Hyades – the Bull’s head. 

During the next few evenings, watch Mars step between the Bull’s Horns, Elnath and Zeta Tauri (ζ Tau on the chart).

This evening, the planet is 3.9° to the lower left of Elnath and 4.1° to the lower right of Zeta Tauri.

The planet is dimmer than it was a several months ago when it was closest to Earth.  Our planet has moved away from the Red Planet, making it dimmer in our sky.

A binocular may assist in viewing Mars with the Bull’s Horns.

This evening the moon reaches its New moon phase at 9:31 p.m. CDT.  It reappears in the western evening sky in a few evenings.  On April 16 and April 17, the crescent moon is near Mars and the Bull’s horns.
