UPDATE:
A significant fireball occurred over Colorado on March 20, 2008 at 8:55 pm MDT ( March 21, 2008 0255 UT )
I was alerted of a large green fireball that occurred over east central Colorado the evening of March 20, 2008.
Upon scrutinizing my video I can see this fireball momentarily lighting up the sky through the clouds.
It makes a great forward scatter reflection with a low toned head echo.
Listen and look closely at the top right section of the screen.
More information to come.
Movie 1 is a 16 second .mov file with the beginning of the sonic scatter reflection:
Movie 2: is a .mp4 file with the full duration of the sonic forward scatter reflection
Note : Both files are large if you are on a dialup connection.
