• At Greenwich civil time 1330, still sailing in the same conditions, the DR position is 23º 27′S 041º 30′W and the Sun’s Greenwich hour angle is 020º 45.7′. Calculate the meridian angle (P).
• At Greenwich civil time 1350, still sailing towards Cape Town, the DR position is 23º 27.2′S 041º 27.2′W, with the Sun’s declination + 00º 39.3′ and meridian angle 15º 41.5′ E. Calculate the Sun’s true azimuth, in circular notation, using the position triangle formulas.
• Having obtained the Sun’s true altitude, with the same Greenwich civil time = 1350, DR position 23º 27.2′S - 041º 27.2′W, meridian angle = 15º 41.5′E and Sun’s declination = +00º 39.3′, work out the Sun’s computed altitude, using the formulas that solve the sides and angles of the position triangle.
