🔍 Key Concepts

• Morning stars and planets visibility relative to the Sun’s position (altitude and azimuth) • Rough positions of Venus, Jupiter, Mars, Saturn in the sky for morning twilight observations • Meaning of ex‑meridian observation and prime vertical in celestial navigation

💭 Think About

• At civil twilight, where is the Sun (altitude and general bearing), and how does that affect which planets are visible and where they appear in the sky? • For a planet to be "near the prime vertical" or "low in the western sky," what must be roughly true about its azimuth and altitude from your latitude? • Which of these planets is typically seen as a bright morning object near sunrise around this time of year, and would it be east or west of the observer?

✅ Before You Answer

• Confirm what civil twilight means in terms of the Sun’s altitude and sky brightness • Recall that an ex‑meridian observation involves a body near the local meridian (near due north or south), not far out on the horizon • Check whether a bright planet described as a "morning star" before sunrise will be seen generally in the eastern or western sky
