Flat Earth Math | Equinox Observations: My informal results: Flat Earth + Globe Earth @FlatEarthMath | Uploaded September 2016 | Updated October 2024, 4 hours ago.
This was completely unplanned, I got to work in the morning and noticed the bright sun through my south facing window, so made shadow-stick sundial and started making marks. At solar noon I was able to participate in Nathan Oakley's 24-hour equinox sun-tracking marathon (link below) and lastly I was able to see the sunset.
