About INDEX
INDEX is a satellite from Japan, launched on Aug 23, 2005 from Tyuratam Missile and Space Complex.
It circles Earth every 95 minutes (15.1 times a day), between 517 and 543 km up, on an orbit tilted 98.0° to the equator, so its path covers latitudes up to 82° 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 517 km to 517 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.
