No more than a dozen times and mostly on a delivery trip from New York
to Tortola. On that trip I remember also putting down pre- and post-
noon GPs on a plotting sheet and swinging the zenith distances with a
drafting compass.

On that same trip I took an extreme altitude sight (Ho 89* 40') which
plotted as a circle around the GP. (Taking the sight had me spinning
too, to find the point of tangency.) But it squared up well with the
DR and I included it in Celestial Navigation in a Nutshell.

At the time of the trip to Tortola I was using a Tamaya NC-2
navigation calculator for the ordinary round of day''s work and
thought of Lat-Lon at Noon as the simplest of the possible celestial
back-stops.
