  3. Spica glimmers demurely under showy Venus in the western twilight. Try for Mercury way down to their lower right. Jupiter and Saturn dominate the evening south.

  4. Venus, Jupiter, and Saturn are all getting a little higher in early evening. Vega passes the zenith soon after dark; Deneb does so two hours later. Andromeda is up in the east.

  5. Jupiter and Saturn are just past opposition, so they dominate the sky all night. They inhabit dim Capricornus, which pushes Sagittarius westward. Venus, even showier, owns the western twilight but sets by full darkness.
