It's possible, but not likely. There are too many variables created by
atmospheric conditions, refraction, and estimating semi-diameter and
when that semi-diameter is on the horizon.

Now azimuth or amplitude of the Sun is easy to find so that you may
correct your compass, but positioning is near impossible.

Subject: [Nml] Sunset sight?

Would it be possible to find position (or at least longitutde), without
a sextant by marking the time at sunset and going to the tables with 0
degrees as the altitude?
