Speedy Mercury is with Jupiter and Saturn low in the west-southwest at about 30 minutes after sunset. Because of the bright twilight, use a binocular to first locate bright Jupiter. Saturn is 2.2° to the lower right of the Jovian Giant. Mercury, brighter than Saturn and dimmer than Jupiter is 1.6° to the lower left of Saturn and 2.8° below Jupiter.
The planets are setting early; this makes the window small to observe them before they disappear below the horizon.
Detailed Note: Thirty minutes after sunset, Jupiter, about 7° up in the west-southwest is 2.2° to the upper left of Saturn. Use a binocular to locate them, especially Saturn. Mercury (m = −0.9) makes a pretty triangle with Jupiter and Saturn. It is 1.6° to the lower left of Saturn and 2.8° below Jupiter. As the sky darkens further, Mars is nearly 60° up in the south-southeast, 4.3° to the upper left of ο Psc and 6.4° below γ Ari. Read about Mars during January.
