Local sky character in Son Tay
Tropical / equatorial latitudes · northern hemisphere · 16 m elevation
- The north celestial pole stands 21.1° above the horizon, so stars within 21° of it never set from here.
- About 68% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 39.9° up, clearing the horizon haze comfortably.
- At 16 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Son Tay is a town-scale settlement, so the edge of the built-up area is often dark enough for the Milky Way on moonless nights.
