    Re: Longitude by observation of the Sun, 19th Century
    From: Peter Cope

    Hi Hewitt,
    Thanks for the response - the LMT of the observations for longitude varied each day, and the calculations for latitude seem to have relied on noon sights except for one day ( I will send that page as well ) backed up by DR from the traverse board. Longitude from the noon sight would not have been very accurate in the prevailing circumstances with a very big sea running, so it would have been difficult to catch the exact moment when the sun was at its height. Though careful records were kept of the 3 chronometers carried, the last comparison, with an observatory, was made nearly a month before.
    If I have trouble attaching pages could you let me have your email and I will scan them.
    Peter Cope
