Altitudes and directions are computed on-device for SCOB (1.3342°N, 103.7357°E) at the chosen moment via the shared astro-core.js engine, so the page works offline. Each figure is listed by its brightest marker star and coloured by family — gold for the Imperishable (circumpolar) stars, cyan for the Unwearying (rising & setting). Sopdet is the star Sirius; its dawn heliacal rising once heralded the Nile flood. See The Egyptian Sky for the figures, the 36 decans and sources.
