This week, the giant planet Jupiter, poised against the stars of Sagittarius, looms up into view low in the southeast in the middle of the night. It rises around 11:30 p.m. local daylight time, and is best seen in telescopes just before morning twilight, when it's fairly high in the south or southeast. A medium-size telescope of high quality on a night of good seeing will show the disk of this creamy white giant richly, though subtly patterned.
