Altitudes, directions and Venus are computed on-device for SCOB (1.3342°N, 103.7357°E) at the chosen moment (Sun & planets via the shared astro-core.js engine), so the page works offline. Each figure is listed by its brightest marker star, coloured by role. Chak Ek', 'the great star', is the planet Venus — morning star (returning Kukulkan) or evening star. See The Maya Sky for the figures, the Venus calendar and sources.
