Two bright planets – Jupiter and Saturn – are low in the southeastern sky before sunrise. Saturn is nearly 11° up in the southeast. Brighter Jupiter – over 6° above the east-southeast horizon – is 10.3° to Saturn’s lower left.
One hour after sunset, the waxing crescent moon is high in the west-southwestern sky in front of the stars of Taurus. The thick crescent is 3.2° to the upper left of Mars and 5.4° to the upper right of Aldebaran.
Use a binocular to inspect the moon’s surface, the Hyades star cluster, and the Pleiades star cluster.
With the binocular find Mars with the dimmer starry background. It is 0.6° above Upsilon Tauri (υ Tau on the chart). Notice that dimmer 72 Tauri (72 Tau) is between them.
Make nightly observations to watch Mars open a gap with υ Tau and move toward τ Tau.
