For figuring the time of LAN you only look at the two sights that have the exactly the same altitude, sights 2 and 11. All the sights that have the same altitude around LAN, sights 5-8 don't help. If you are faster with the sextant you could have had a lot more sights with that altitude. For figuring LAN you take the two sights that have the exact same altitude and that are spaced as far apart as possible. It looks like you misread the time for sight 2, you put 18-02-45 and the correct time is 18-02-05, the average is 18-07-46. Plus ZD minus WE makes the GMT of LAN 22-07-41. Since your time is 4 seconds too soon your longitude is one minute to far to the east so add one minute to your answer and you have it. gl --- On Mon, 11/28/11, Mike Burkes <m_burkes@msn.com> wrote:
