In the evening sky, Jupiter continues to inch away from Saturn. This evening’s gap is 0.3°. It’s still narrow, but the change is easily observed. Jupiter is moving eastward faster than Saturn, in front of the starry background.
Look for them low in the sky from about 45 minutes after sunset until about 90 minutes after local sunset before they disappear below the southwestern horizon.
Meanwhile, farther east, the gibbous moon is about 13° to the lower left of the moon in the southeast as night falls. The chart above shows an exaggerated view of the sky with many stars in the region of Mars and the moon. To see them, a binocular is necessary to see the stars with the bright moonlight.
