About NIMBUS 3
NIMBUS 3 is a satellite from the United States, launched on Apr 14, 1969 from Air Force Western Test Range.
It circles Earth every 107 minutes (13.4 times a day), between 1,070 and 1,129 km up, on an orbit tilted 99.7° to the equator, so its path covers latitudes up to 80° north and south.
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 1,069 km to 1,070 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
