En aguas del Atlántico Norte, cercanas a Canarias, el día 28 de Marzo de 2020, por la mañana, en situación estimada 30º 10,7’N 015º 10,0’W, obtenemos previamente del Sol los siguientes datos:  Declinación= +03º 15,8’  Ángulo en el Polo ( P)= 27º 40,2’ E Calculamos el valor de la altura estimada del Sol utilizando las fórmulas que resuelven los lados del triángulo de posición ...In the North Atlantic, near the Canaries, on 28 March 2020, in the morning, at DR position 30º 10.7’N 015º 10.0’W, we first obtain for the Sun: Declination = +03º 15.8’; Angle at the pole (P) = 27º 40.2’ E. We calculate the computed altitude of the Sun using the formulas that solve the sides of the position triangle.
