Reference · Passes: when a satellite crosses the sky over a place

VisibleParttype

The part of a pass a person can see: from when the satellite is lit, the sky is dark enough and it is bright enough and above the lowest altitude, to when one of them stops; and the highest point of that part. It is what a sky-watcher's table lists as the pass.
