Observer: Detroit, Michigan. Both panels use the same date and time and the same 360° azimuth-elevation projection.
Globe: Sun rises, crosses the sky, sets below the horizon and disappears at night.
Flat-Earth: 32-mile Sun at 3,000 miles altitude circles above a North-Pole-centered disk and remains visible somewhere in the panorama for the full 24-hour cycle.
Sun disks are enlarged for visibility; relative apparent sizes are preserved.
