    George,

    I'm not familiar with Wakeley's "Mariner's Compass Rectified," but think that might have done the job for Scoreseby.

    Sunset in the arctic would be a gradual process. Perhaps that explains why Scoreseby used the sun's upper limb. The "now you see it, now you don't" of the last glimmer would have been the most easily defined moment.
