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.
