109. On 13 October your 0515 zone time (ZT) fix gives you a position of LAT 26°53.0'N, LONG 90°05.0'W. Your vessel is on course 068°T, and your speed is 7.8 knots. Local apparent noon (LAN) occurs at 1145 zone time, at which time a meridian altitude of the Sun's lower limb is observed. The observed altitude (Ho) for this sight is 54°51.5'. What is the calculated latitude at LAN?
The correct latitude at Local Apparent Noon (LAN) is 2712.6'N, determined by calculating the zenith distance from the observed meridian altitude and applying the appropriate formula considering the contrary relationship between latitude and declination.
