About UMBRA-11
UMBRA-11 is a satellite from the United States, launched on Nov 28, 2025 from Air Force Western Test Range.
It circles Earth every 94 minutes (15.3 times a day), between 470 and 472 km up, on an orbit tilted 97.4° to the equator, so its path covers latitudes up to 83° 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 11 days its lowest point went from 472 km to 470 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.
