“[T]he feature that was most mentioned was the vivid green color mentioned by many witnesses,” the American Meteor Society said.
Indeed, eyewitness reports to the Capital Weather Gang described a vivid green trail in the western sky.
“Several Chicago area photographers, among them David Whitfield, managed to videotape the fireball which included a “tail” despite a thickening overcast over the city when the object passed overhead around 5:23 pm Monday evening,” writes meteorologist Tom Skilling at the ChicagoWeatherCenter.com.

Fireball over Japan
Reports the Japan Times: Observatories and other bodies received a number of reports of a fireball-like object in the skies over western Japan on Monday night, with experts saying it was likely a bolide — a very bright shooting star.
Here’s some useful background on the phenomenon from the America Meteor Society:
A fireball is a meteor that is larger than normal. Most meteors are only the size of tiny pebbles. A meteor the size of a softball can produce light equivalent to the full moon for a short instant. The reason for this is the extreme velocity at which these objects strike the atmosphere. Even the slowest meteors are still traveling at 10 miles per SECOND, which is much faster than a speeding bullet. Fireballs occur every day over all parts of the Earth.
