    Re: Lat/Lon by "Noon Sun" & The Noon Fix PROVE IT

    I'll attach my results from your first data set. To do more, I would have to automate it, since I'm lazy. Rather than prolong this event, I fudged and used regression analysis to fit lines through your data. The scatter was beyond what my eyeballs could handle.
    The results are:  Lat, 56°12.2'N, Lo, 9°53.6'W.
    As I examine the plot, I realize that I have committed the sin of extrapolation,
    i. e., the intersection of the lines is outside of the data range. In this case, I should have used data over a longer period. That should have moved the time of LAN a bit earlier. If I use the plot from my Navigation paper, the time difference between maximum altitude and LAN is 4m50s. That moves LAN earlier by 15s, consistent with the above.
    I enjoyed the learning, and I got quite a bit of that.
