I am slowly teaching my self celestial navigation. I have a copy of
Dutton, which many of you on this list recommended to me, and a
downloaded copy of Bowditch. I am working my way through noon sight and
grasping the concepts, the online almanacs I am finding to be pretty
good and easy to understand.
Now I come to my problem. I downloaded a problem from the website
www.oceannavigator.com entitled "Navigating without a clock." This
problem deals with a noon sight to determine latitude but there is no
clock on the ship. Lest anyone get to worried, the author of the
problem does make several assumptions to make the problem solvable.
I have looked in a number of places for a paper and pencil method to
determine GMT as well as sunrise and sunset. I have found a basic
computer program from Sky and Telescope magazine in 1994 which shows how
to determine sunrise and sunset at a selected position, but so far no
way to determine noon GMT. I know that this information is provided in
the nautical almanacs on the daily pages, but I am looking for a way to
calculate this number using a pencil and paper. I have a pretty good
feeling this is going to be somewhat difficult, but I am willing to make
the attempt. I know that there are spreadsheets, and computer programs
capable of doing this, but I am looking for pencil and paper
If anyone can direct me to a reference or a guide either online or in
print I would greatly appreciate it.
I will keep plugging away at this. Thanks for all your help.
Andrew
