More than 60 eyewitnesses filed sightings on the American Meteor Society's website.
Greg Moore, an analyst and contributor at Weather5280, told Mashable he was driving over the top of Vail pass, west of Denver, just before 6 a.m. local time when "a bright green fireball caught my eye."
The object had a "flaming tail with a long trail behind it," Moore said. "As it moved towards the far horizon it started to flame out, but even after the tail was gone a bright orange ball was still visible till it disappeared beyond the far mountain range."
"It was pretty incredible," he said.
Snapchat user Joel Jimenez sent Mashable video he caught from a Home Depot parking lot in Fort Collins.
Brian Paulson, a software engineer, caught the fireball on his car's dash cam while driving about 15 miles north of Pueblo, Colorado. A second man caught it on his dash cam from Denver.
Colorado resident Nate Hershey told Mashable he was getting his kids dressed on Wednesday morning and happened to look out the window when the object was streaking across the sky.
"The head was bright white, and it had a deep orange tail with what looked like sparks falling behind, moving very slowly for a meteor," he said.
"I had time to put my 1 year old down, grab my four year old, climb onto my bed and hold him up to the window for a few seconds before it faded," Hershey said. "At the end, the tail appeared to be an eerie green with a slight blue tint as it disappeared."
"I've seen a lot of meteors in my day but this must have been the most spectacular, lasting for what seemed like around 10 seconds," he said.
The fireball, which could have been a meteor, satellite debris or a warning shot from an alien warship, was first reported on Twitter.
Maybe I am missing something or reading it as a street light? However SoTT are to be congratulated on ending their endless parade of aircraft contrails in this section over the past few weeks. Maybe I (and others) are getting somewhere at last?
