Shows the sun's position over a flat Earth projection
The red dot is your observer position (adjustable with lat/long controls)
The yellow dot is the sun's current position

Observer's View
Shows what the observer sees at their position
The horizon line shows North → East → South → West
The yellow circle represents the sun's position relative to the observer
Red dots show the analemma pattern (sun's position at solar noon throughout the year)
Controls
Play/Pause: Animate the sun's movement through the day
Time Slider: Manually set the time of day (24-hour format)
Animation Speed: Adjust how fast the sun moves (1x to 100x speed)
Looking South/North: Change the observer's viewing direction
Full View/Half View: Toggle between ±180° and ±90° view
Sun Trace: Show the sun's path throughout the day
Generate Analemma: Show sun's position at solar noon for entire year
Measurements & Analysis
All angles and positions are calculated based on the flat Earth model
The data panel shows sun position, angles, and distances
Units can be toggled between kilometers and miles
The analemma shows simple up and down movement predicted by flat Earth theory
Compare this vertical pattern with the figure-8 analemma observed on globe Earth
