    You haven’t missed anything. But I did. I use “centre coincidence ” when taking AH sun sights and had forgotten the other possibility, “limb touching”, though I now remember having read about it. I don’t know which to prefer. John Karl (Celestial Navigation in the GPS age) describes only the first method. Bowditch, 1958 and 1977, both.

    Thanks to Brad and Stan for clarifying messages.
