The Daily Circuit
Each day, the sun completes a full circular circuit above the flat earth plane, centred on the North Pole. The sun travels eastward (when viewed from above the North Pole, anticlockwise) in a loop approximately corresponding to the latitude over which it currently sits — tropical regions in summer, equatorial regions at equinox, and deeper southern circuits in winter for Northern Hemisphere observers. The circuit takes approximately 24 hours to complete and is driven by the sun's own motive force within the electromagnetic system of the firmament, not by Earth's rotation.
From any fixed observation point on the flat Earth, the sun appears to rise from the east, arc across the sky, and set in the west. This is perspective in action: the sun is always at the same altitude (approximately 3,000 miles), but as it approaches from the eastern portion of its circuit, it appears to "rise." As it departs toward the western portion of its circuit, it "sets." No actual rising or setting below a curved horizon occurs — the sun recedes to the perspective vanishing point.
Speed and the Circle
If the sun circuits the Tropic of Cancer (approximately 16,500 miles circumference on the FE disc at tropical latitude), it travels approximately 690 miles per hour. At the equatorial circuit (approximately 25,000 miles), it travels approximately 1,040 mph. These speeds are consistent across the model and produce the measured solar apparent speed of approximately 15° per hour across the sky — which is the same at all latitudes, consistent with a circuit model where the sun's angular speed as seen from Earth stays constant as it completes its prescribed loop.
Psalm 19:4-6 describes the sun: "In them hath he set a tabernacle for the sun, Which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race. His going forth is from the end of the heaven, and his circuit unto the ends of it." The Hebrew word for circuit is tequphah — a revolution, a circuit. The biblical sun runs a circuit. It does not orbit a distant star system at 67,000 miles per hour.
The Annual Spiral and Why Seasons Happen
Over the course of a year, the sun's daily circuit diameter gradually changes. At the June solstice, its circuit is closest to the North Pole — above the Tropic of Cancer. At the December solstice, its circuit is at its largest diameter — above the Tropic of Capricorn. This annual outward-and-inward spiral is the mechanism of seasons: proximity to the Tropic of Cancer circuit (Northern summer) brings longer days and direct overhead sun to Northern Hemisphere observers; the Tropic of Capricorn circuit (Southern summer) does the equivalent for the outer regions of the disc.
Sunrise and Sunset by Perspective
The sun does not go below a curved horizon. It recedes toward the vanishing point. At the limit of optical resolution (naked eye or standard camera), the sun appears to "dip" below the visible reference line. With a powerful enough zoom lens on a clear day, the "set" sun can be brought back into view — still above the horizon, just at the limit of perspective visibility.
The Same Time Zone Impossibility
Time zones on the globe model are explained as Earth's rotation carrying different regions into sunlight. On the flat Earth, time zones are real — but they are caused by the sun's distant position relative to observers: the sun is over the East at 6am Eastern time because it is circuiting in that region of the flat plane. As its circuit carries it westward past noon positions, the time changes. The mechanism is different but the observations are identical.
