It happened quick but it was big compared to things we normally see in the sky. I've only seen something like this once before and that was about 7-8 years ago when I lived on the south side of Richmond.

Remarks
I'm not sure exactly what you are asking here. This was a big blueish fireball. It was many many times larger than anthing we see in the sky except for the moon and the sun. It was like a 100 times bigger and brighter than the stars we see (except the sun of course). It was about 1/8 the size of a full moon. It did seem to have somewhat of a tail but It seemed to disappear with the ball.

Remarks
I saw this fireball in the sky moving approx. NNW and heading downward. It seemed to just disappear at about 25 degrees above the horizon.
