Estando en situación de estima: le = 43º 56,8’ N y Le = 045º 39’ W, se observa el Sol a su paso por el meridiano superior del lugar con una altura verdadera meridiana avmʘ = 62º 25,0’, siendo su declinación dʘ = +16º 22,9’ Calcular la latitud observada.At DR position le = 43º 56.8’ N and Le = 045º 39’ W, the Sun is observed on the upper meridian with a true meridian altitude of 62º 25.0’, its declination being +16º 22.9’. Calculate the observed latitude.

Show the answer

Correct answer: d) lo = 43º 57.9’ N

Why it is correct

z = 27º 35.0′. l = 16º 22.9′ + 27º 35.0′ = 43º 57.9′ N.

Why the others are not

  • a) It does not match the working.
  • b) It does not match the working.
  • c) It does not match the working.

How to work it out in the exam

  1. z = 90º − a.
  2. Facing south: l = d + z, with south d negative. Facing north: l = d − z.
