    Timesight near sunset?
    From: Bruce J. Pennino

    Hello:
     
    Just thinking further about this......  Until this problem, I never really noticed that the altitude correction table was really two tables,  10-90 and 0-10 degrees.  I never thought about it because I read somewhere it is "bad" practice to measure altitudes less than 20 degrees or so. We had good results with a time sight at sunset- a negative angle.  Also, I've had good results  with LOPs measuring altitudes of 12- 15 *.   This begs the question.... For reasonable results of +/- 7 NM, what is the smallest sun sight altitude that can be measured with a good horizon? Must be using an ordinary sextant, not one that measures to 10 seconds!
     
    What if you are an explorer at 66* north this time of year?  No noon sight? Depend on stars?  Just thinking aloud!

    Indeed. I was standing on the  beach at Spencer Beach County Park in Kawaihae. :)

    Marcel,

    If the given latitude is correct then the intersection on the western shore is at 155* 49.5' W (Kawaihae). A place with some history.
