Examples
What it can do.
35 reconstructions. None of them is a video: each is computed while you watch it, from a real date, a real hour and a real place — choose where to start.
Real sightings
Documented cases, each replayed in the sky of its own reported date, time and place.
What the sky contains
Haloes, rainbows, the Milky Way, a comet, a nova, meteors, satellites, a fireball: one sight at a time.
Instrument and weather
The same sighting through an eye, an Instamatic and a reflex; a storm; an airliner on a long exposure.
What is not here yet#
Observing from an aircraft, radar propagation anomalies. What each one is waiting on is on the roadmap.
