Next message: Bill: "Re: Voyaging the traditional way"
Alex,
Raper's "Practice of Navigation" has three pages on Finding the Longitude by
Occultation. Here are two passages, one near the beginning, the other at the
end:
"This observation affords, in favorable cases, the most decisive results,
because it is both instantaneous and altogether independent of instrumental
adjustments."
"The case least liable to error on the several accounts enumerated are those
which occur when the moon is near the meridian, and in which the central zone
of the moon passes over the star. The emersion from the dark limb is the case
most distinctly marked."
If you like, I'll send you photocopies of the three pages. But you'll have to
send your US mail address soon, as Janice and I are leaving again shortly,
and will be gone for several weeks.
