    Re: Timesight at sunset?

    This was an excellent problem because it forced me to  carefully reread John Karl's  book section - "St. Hilaire without a Sextant".
    I used a calculator (also made me careful with signs) . Even  with my 1 minute mistake in reading table A4 I had an answer 4NM east of Spencer Beach County Park.  Good enough !
    The time sight  equation cosine LHA = ......... is really quite powerful.
    Now the trick is really to get the exact  time that the apparent  shimmering sun goes below the horizon. Not so easy or exact.
    Thanks Doug

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

    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.
