About LES 6
LES 6 is a satellite from the United States, launched on Sep 26, 1968 from Air Force Eastern Test Range.
It sits in geostationary orbit about 35,800 km above the equator near 105°W, turning with Earth so it stays over the same spot.
The map shows where it is right now; the pass list tells you when it next comes over your location.

Orbit height over the past year
Over the last 10 days its lowest point went from 35,730 km to 35,729 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
