twilight shadowing

vendingmachine commented on the word twilight shadowing

James Oberg explained many UFO sightings on the Internet. Most of them belong to one of three groups:

super-high plumes – rocket or missile plumes, especially lit by Sun on a dark sky;

space dandruff – ice flakes, fragments of insulation, etc. flying alongside a space vehicle, especially seen on backward-facing camera;

twilight shadowing – objects that move from shadow into sunlight in space appear as if coming from behind the clouds or from beyond the edge of the Earth.
