Neat. At some later point you might do one that takes the measurement at the same time (obviously that would leave out that half of the globe that is experiencing night!) and plot the angles and bearings. Plotted onto a globe, if the Earth is a globe with a distant Sun you would expect lines that are essentially parallel. Plotted onto a plane, if the Earth were flat with a “local Sun,” they would be expected to converge on a single nearby point. Plotting the data onto the incorrect model should not provide the predicted results.
Thanks for the option of leaving data here ... Read even more
