Hello Navigators, I am currently on a ship and was wondering if the members of the board would like some real-life sights to work out? I will supply the data and then people can run the numbers using whatever method and post results. Here is one from today, and it's a simple LAN problem. A ship is adrift near the island of Saipan, in the north Pacific. The noon position is Lat 15-14'N and Long is 145-40'E on 5/16/08 (ZD -10) A) Calculate time of LAN, Az of the sun, and approximate Hc. A sight of the sun (LL) is observed at 1213-40L. Sextant altitude was 85-59.0'. Height of eye was 106 ft, IE is 0.8' off the arc. Temp was 93 deg F Barometer was 1012 MB. B) Determine Latitude by LAN.
