🔍 Key Concepts

• Prime vertical: the vertical circle that passes through the east and west points of the horizon • Relationship between observer’s latitude and body’s declination for rising/setting vs. crossing the prime vertical • Meaning of same name vs contrary name (N/S) for latitude and declination

💭 Think About

• Think about when a body can pass exactly due east or due west of you. How must its position on the celestial sphere compare with your own latitude? • What changes if the body is on the same side of the equinoctial (same name) versus the opposite side (contrary name)? • If the declination is very large compared to your latitude, is it still possible for the body to cross your due east–west line, or will it always stay to one side of it?

✅ Before You Answer

• Be clear on same name vs. contrary name: N/N or S/S is same name; N/S is contrary name • Visualize (or sketch) the celestial equator, your zenith, and the body’s declination circle and ask when that circle can intersect the prime vertical • Check whether the condition must be latitude greater than or less than declination for an intersection with the prime vertical to occur
