In celestial navigation, we are interested in the smaller of these, the spherical triangle which has the smaller angle between the meridian of the celestial body and the meridian of the 5 observer.

WebLet the angular distances along the great circle from A to P1 and P2 be σ 01 and σ 02 respectively. Then using Napier's rules we have (If φ 1 = 0 and α 1 = 1⁄2 π, use σ 01 = 0). This gives σ 01, whence σ 02 = σ 01 + σ 12 . The longitude at the node is found from Figure 2. Web19.
