About CORIOLIS
CORIOLIS is a satellite from the United States, launched on Jan 6, 2003 from Air Force Western Test Range.
It circles Earth every 101 minutes (14.2 times a day), between 815 and 836 km up, on an orbit tilted 98.7° 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 24 days its lowest point went from 816 km to 815 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
From Space-Track element sets, one point a day.
