Jupiter and Saturn continue their slow climb into the morning sky. They are low in the southeastern sky before sunrise. Forty-five minutes before sunup, Saturn is nearly 10° above the southeast horizon. Brighter Jupiter, only 5.0° in altitude in the east-southeast, is nearly 11° to the lower left of Saturn. Both are slowly moving eastward in their orbits compared to the background stars. The gap between them continues to grow after their great conjunction over three months ago.
As night falls, the bright moon – 74% illuminated – is high in the southern sky. It is 9.0° to the lower left of Pollux. The bright lunar orb is among the dim stars of Cancer.
Mars, marching eastward, is over halfway up in the west-southwest in front of the stars of Taurus. Tonight, it is to the upper right of the “V” of Taurus that is made by Aldebaran and the Hyades star cluster. The Red Planet is 1.0° to the lower right of Tau Tauri (τ Tau on the chart).
With tonight’s bright moon, a binocular may be needed to see the dimmer stars. Alternately, step into the shadow of a house or other structure to help block the moon’s light to see the dimmer stars in Taurus.
As Mars moves eastward it passes τ Tau and continues to move toward the horns of the Bull, Elnath and Zeta Tauri (ζ Tau). The planet splits the gap between the stars next month.
