How to spot the ISS from San Cristóbal de las Casas
San Cristóbal de las Casas sits at 16.73°, -92.64°. The brightest passes typically appear within 1–2 hours of sunset and again before sunrise, when the satellite is sunlit while the sky above San Cristóbal de las Casas is dark. Look for a steady, fast-moving point of light brighter than most stars — the ISS rivals Venus at peak.
The table above lists every pass tonight reaching at least 10° elevation. Get away from direct streetlights for the best view; binoculars help but none of these passes require a telescope.
