The sky over Athens, Greece, 6/21/-1158,

as computed by John Walker's Home Planet program.

The orbital elements for the fictitious comet 'Phaethon' are based on the real Earth approaching object Oljato, which is thought to be an inactive comet.

The animation runs from 02:45 AM UTC with an Earth-comet distance of .005AU to 11:42 AM UTC with a very close pass to the aft of Earth. The first nine frames are one hour apart (02:45-10:45). The next image is at solar transit (11:15) followed by a view fifteen minutes later (11:30), then the next two frames are five minutes apart (11:35 and 11:40). A last image two minutes later (11:42) finishes the sequence. Intervals between successive frames are adjusted proportionately to reflect this non-linear sequence.
