Fireball over Colorado Answered
What are the odds? On Oct. 28th at 7:29 pm Mountain Daylight Time, a random meteoroid hit Earth's atmosphere and disintegrated with the luminosity of a full Moon. The impact, which could've happened anywhere, took place directly above an all-sky video camera in Guffey, Colorado.
"I've received more than 100 eyewitness reports," says astronomer Chris Peterson, who operates the camera as part of a nightly fireball monitoring program. Combining the data at hand, he estimates that "the meteor had a ground path about 170 miles long and traveled from east to west at 34 km/s (76,000 mph)."
"I was lucky enough to see it myself from inside my house through a window," adds Thomas Ashcraft. What's amazing about that is he was located 300 miles away in New Mexico. "It was brilliant turquoise and green and lasted more than nine seconds." Ashcraft is an amateur radio astronomer and his receivers picked up echoes of distant TV transmitters bouncing off the fireball's ionized trail: listen.
Using a computer model of Earth's meteoroid environment, Bill Cooke of the Marshall Space Flight Center calculates that fireballs this bright come along once every five months or so. Rarely, however, are they witnessed. About 70% of all fireballs streak over uninhabited ocean while half appear during the day, invisible in sunny skies. To catch one in the crosshairs of a meteor camera on a dark albeit cloudy night is good luck indeed.
Other observers caught video of the event, and recorded the radio noise it made.
You could have recorded the event yourself, if you had followed this Instructable.
