After all these years 50, I can’t remember everything, but it was simply to use our DR Longitude and go in to the Almanac for the sun GHA and GMT equal to Longitude. Subtract or add 28 minutes for the shot. Then work the EX-meridian and sun line for the fix. Sometimes wait and work the true LAN. I don’t remember any real difference in EX or LAN. The Outpost was not going anywhere just staying on station.
This is where I started using my VERTICAL SEXTANT. Has anyone tried that? I think with a good sextant and horizon, even with the narrow 7-8 degrees the LOP intersection will only be off a few miles. You can even do a can problem on a chart to evaluate the situation of the small angle fix without doing the actual sight.
