Re: Celestial Navigation: Nautical Almanac

Nice. That's what practice is for.

By the way, if Procyon's computed LHA is 358°58.4' then I think it makes more sense to round up to 359° for the purpose of indexing Pub 249, no? That means you should use the row above.

Also, you need to interpolate between 5° and 6° of declination. If your computed declination has 11.4' attached, and d = 60', then you need to add 11.4' to Hc, which brings you up to Hc = 43°11.4'. This is a lot closer to your Ho of 42°38.2'.
