    I'm working on a simple tool to visualize the Sun position above the AE ("Gleason") map with the direction the Sun is actually visible on the sky ("azimuth angle") to see that most of the time the Sun would not be in the direction we would see it if the AE map accurately represented reality.

    Currently the tool is hosted here: https://oudeicrat.github.io/ (this might change in the future and this link will be updated)

    The calculated Sun position can be verified on timeanddate.com (a link is provided) and the calculated azimuth angle can be verified on suncalc.org (a link is provided)

    For example when looking at the sunrise from London during March equinox (2019-03-20 06:04)
    we see that the Sun is visible almost directly on the East (azimuth ~90 degrees) while the Sun is above 91 degrees of latitude.

    This can be verified with two generated links (the "check" links):

    I'll be adding more description and screenshots later here

    Known bugs: (last update 2019-01-24)
    - for some areas (especially the oceans) the timezone offset is not available on timezonedb.com, so I can't generate a proper link to suncalc.org to verify the azimuth angle

    please report any bugs you notice or maybe even improvements or feature suggestions

    great suggestion, done :)

    it accepts the UTC date and time entered in the text-box and shows where the Sun would be at that date and time. It's labeled "UTC" to ensure people will realize it's a UTC time, not a local time relative to their timezone or the timezone of the selected location on the map

    I added animation, sun coverage / night indication, a couple of "checkpoints" (visualization of sun direction from other points on the map) and predefined dates for the equinoxes and solstices:

    Very nice, good visual tool to show how the sun could never match the reality that we can see, from anywhere at any time. Particularly for locations on or near the equator which clearly demonstrates the impossibility of the AE map and confirmable reality. I really don't see how this could be refuted other than ignore it.

    Could this be done for the moon as well, perhaps even a moon phase visualisation, is what we see in reality against what we should see as per AE map as well, wouldn't be surprised the AE map should enable seeing the far side of the moon.

    After running some scenarios for Australia or any southern hemisphere locations, it clearly demonstrates the wackyness of the AE scenario. Rises from opposite directions, seemingly close to reality in mid morning till mid afternoon then setting in the opposite direction. Of course, if you live in the southern hemisphere you can poo poo it by getting up at 10 am and going to bed at 4 ish.

    Even assuming the flerspective explanation for sunrise and sunset, which somehow makes the Sun invisible during part of its "orbit" over the FE: During the months when there is more than 12 hours of daylight, you would be seeing the Sun as it passes through more than 180 degrees of its orbit. Which means there would be a retrograde motion during the morning and evening.

    I think they get around this by saying that the moon is self-illuminating, therefore its phases aren't caused by the sun.
