About NOAA 9
NOAA 9 is a satellite from the United States, launched on Dec 12, 1984 from Air Force Western Test Range.
It circles Earth every 102 minutes (14.2 times a day), between 825 and 845 km up, on an orbit tilted 99.1° to the equator, so its path covers latitudes up to 81° 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 365 days its lowest point went from 826 km to 825 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
