Fireball Event Over Colorado : October 29, 2008

I was fortunate to eye-witness this particular fireball event which happened
over central Colorado. This is over 300 miles north of my location
in north central New Mexico! I was inside the house and saw it through a
window. The fireball was turquoise to brilliant green
with a long trail and it shed sparks. It lasted over 8 seconds visually
and traveled from East to West with a possible
slight northwesterly heading. More information from Colorado should
be forthcoming soon.
Please send any eyewitness accounts to me. Thanks! : Thomas
In the movie below the fireball is rather unimpressive at the very top of
the screen. But know that it is at the farthest edge of my visual range.
My dual radio forward scatter array caught the sonic event on both channels
and if you look at the movie closely you can see the
fireball flare and hear the radio reflection flare simultaneously. It made
a "whooping" sound at one point on one channel.
Turn up the sound and listen closely!
