A bright white fireball in the N about 1k high, fell to the NE it was about to hit houses and vanished, lasted15 secs.On February 5, 2009. 5:24 P.M.I was standing outside on the porch enjoying the fresh air.I was looking to the north when I saw a large ball of fire. It really startled me because it didn't look like it could be more then 1,000 feet high in the sky.Looking directly at it the size might have been the size of 2 basketballs put together. I used my neighbors roof peak to give the fall a direction. If the peak of their roof was 12 o'clock the fireball fell to 3:30 in 10-15 seconds. I ran from the porch to the sidewalk. Just when I thought it was going to crash into the houses about 1/2 block north of where I was standing it went poof and was gone. By poof I mean that it got dim and just disappeared. It didn’t shatter or fall apart, it just got dim and was gone.The fireball itself was a bright white and the flames around the outside were neon lime green closest to the circumference then neon yellow and finally a very bright orange. (The orange wasn't as intense as the other colors.) I have never seen anything burn with those colors, as you are familiar with flame at the orifice of a gas burner it is the hottest at the very brightest blue, the gets cooler as you move away.I checked the San Diego newspaper the Union Tribune for 2 days and there was nothing mentioned about what I saw.
