In [NavList 6768] and [NavList 6796] Frank and Dave gave us the graphical solution.
Here is the analitical one.
For the planets the SD and Parallax(HP) corrections to clear the LD haven`t taken into account.

If you grabbed your sextent (or your octant, or your quadrant, or your protractor and string) and made the following near limb distance observations at 20:00:00 UT 2008 Dec 1: Venus 1 deg 16.9 min, Jupiter 1 deg 35.3 min, what island would you be near?
