Q

At evening stars, the last stars that should be observed are those with an azimuth in what quadrant?

🔍 Key Concepts

• Evening stars observations and how sky brightness changes after sunset • The relationship between a star’s azimuth and how long it remains visible as twilight progresses • Which horizon (E, S, N, W) darkens last during evening twilight for an observer at sea

💭 Think About

• Think about where the Sun has just set at evening twilight and which part of the horizon stays bright the longest. • If you want to see a star for the longest possible time before it fades into twilight, should it be closer in azimuth to the bright part of the sky or the darker part? • Imagine standing on deck at evening stars: as the western sky dims, which quadrant’s stars will still be clearly visible last?

✅ Before You Answer

• Be clear on how azimuth quadrants are defined: Eastern (045°–135°), Southern (135°–225°), Western (225°–315°), Northern (315°–045°). • Visualize the Sun setting and track which azimuth quadrant is opposite that point on the horizon. • Confirm which part of the sky becomes dark first and therefore allows star sights the longest during evening (not morning) twilight.
