Select an occultation, extract timings from Occult and subset to one geographic area.

Add a “blue dot” at each observer’s location.(This requires translating latitude and longitude
into X and Y coordinates on the After Effects screen.)

Adjust the timeline of the animation to matchthe actual time period of the occultation.
Adjust the Opacity property of each blue dot “positive”so it disappears at the actual D time and
reappears at the actual R time.
Blue dots which are “negatives” stay at 100% opacity.

That’s it!You can manually add the asteroid shadow and
animate it to come close to the actual path if you wish
